# curl_setopt

(PHP 4 >= 4.0.2, PHP 5)

curl_setopt -- Устанавливает параметр для сеанса CURL

## Описание

bool curl_setopt ( resource ch, string option, mixed value )

Функция curl_setopt() Устанавливает параметр для сеанса CURL, заданного аргументом `ch`. Аргумент `option` задает устанавливаемый параметр, а `value` - его значение.

Для перечисленных ниже параметров, `value` должен быть целым числом:

- `CURLOPT_INFILESIZE`: при закачке файла на удаленный сервер, следует использовать этот параметр для указания ожидаемого размера файла.

- `CURLOPT_VERBOSE`: При установке этого параметра в ненулевое значение cURL будет выводить подробные сообщения о всех производимых действиях.

- `CURLOPT_HEADER`: При установке этого параметра в ненулевое значение результат будет включать полученные заголовки.

- `CURLOPT_NOPROGRESS`: При установке этого параметра в ненулевое значение не будет выводиться индикатор прогресса операции.

  > Замечание: В PHP этот параметр устанавливается в ненулевое значение по умолчнию. Изменять его значение рекомендуется только при отладке.

- `CURLOPT_NOBODY`: При установке этого параметра в ненулевое значение результат не будет включать документ (например, вам нужно получить только заголовки).

- `CURLOPT_FAILONERROR`: При установке этого параметра в ненулевое значение, получение HTTP кода более 300 считается ошибкой.

- `CURLOPT_UPLOAD`: Установка этого параметра в ненулевое значение означает, что будет производиться закачка файла на удаленный сервер.

- `CURLOPT_POST`: При установке этого параметра в ненулевое значение будет отправлен HTTP запрос методом POST типа `application/x-www-form-urlencoded`, используемый браузерами при отправке форм.

- `CURLOPT_FTPLISTONLY`: При установке этого параметра в ненулевое значение будет получен список файлов в директории FTP сервера.

- `CURLOPT_FTPAPPEND`: При установке этого параметра в ненулевое значение данные будут добавляться к файлу на FTP сервере, в противном случае файл будет перезаписан.

- `CURLOPT_NETRC`: При установке этого параметра в ненулевое значение будет сделана попытка найти имя пользователя и пароль к удаленному серверу в файле `~./netrc`.

- `CURLOPT_FOLLOWLOCATION`: При установке этого параметра в ненулевое значение, при получении HTTP заголовка "Location: " будет происходить перенаправление на указанный этим заголовком URL (это действие выполняется рекурсивно, для каждого полученного заголовка "Location:").

- `CURLOPT_PUT`: При установке этого параметра в ненулевое значение, будет производиться закачка файла методом HTTP PUT. Файл задается параметрами `CURLOPT_INFILE` и `CURLOPT_INFILESIZE`.

- `CURLOPT_MUTE`: При установке этого параметра в ненулевое значение, все сообщения cURL будут подавляться.

- `CURLOPT_TIMEOUT`: Задает масимальное время выполнения операции в секундах.

- `CURLOPT_LOW_SPEED_LIMIT`: Задает минимальную скорость передачи в байтах в секунду. Если в течении времени, заданного параметром `CURLOPT_LOW_SPEED_TIME`, скорость передачи будет меньше этого значения, операция будет прервана.

- `CURLOPT_LOW_SPEED_TIME`: Задает время в секундах, в течение которого скорость передачи должна быть ниже, чем `CURLOPT_LOW_SPEED_LIMIT`, чтобы операция была признана слишком медленной и прервана.

- `CURLOPT_RESUME_FROM`: Задает позицию в файле в байтах, с которой начнется передача данных.

- `CURLOPT_CAINFO`: Имя файла, содержащего один или более сертификатов, которые будут использованы при проверке подлинности удаленного сервера. Имеет значение только совместно с параметром `CURLOPT_SSL_VERIFYPEER`.

- `CURLOPT_SSL_VERIFYPEER`: Установите этот параметр в ноль, чтобы запретить проверку сертификата удаленного сервера (начиная с curl 7.10, по умолчанию этот параметр имеет значение `TRUE`). Дополнительные сертификаты можно задать с помощью параметра `CURLOPT_CAINFO` (добавленного в in curl 7.9.8). Можно также указать путь к файлам сертификатов в параметре `CURLOPT_CAPATH`. Если `CURLOPT_SSL_VERIFYPEER` установлен в 0, возможно, также потребуется установить `CURLOPT_SSL_VERIFYHOST` в 1 или 0 (по умолчанию 2).

- `CURLOPT_SSLVERSION`: Целое число, указывающее, какую версию SSL использовать (2 или 3). По умолчанию версия SSL определяется автоматически, но в некоторых случаях требуется явное указание.

- `CURLOPT_SSL_VERIFYHOST`: Задает проверку имени, указанного в сертификате удаленного сервера, при установлении SSL соединения. Значение 1 означает проверку существования имени, значение 2 - кроме того, и проверку соответствия имени хоста.

- `CURLOPT_TIMECONDITION`: Задает способ интерпретации значения параметра `CURLOPT_TIMEVALUE`. Возможные значения: TIMECOND_IFMODSINCE или TIMECOND_ISUNMODSINCE. Применяется только для протокола HTTP.

- `CURLOPT_TIMEVALUE`: Задает время в секундах с 1 января 1970 г. Это значение будет использовано в соответствии со значением параметра `CURLOPT_TIMECONDITION` (по умолчанию TIMECOND_IFMODSINCE).

- `CURLOPT_RETURNTRANSFER`: При установке этого параметра в ненулевое значение CURL будет возвращать результат, а не выводить его.

Для перечисленных ниже параметров, `value` должен быть строкой:

- `CURLOPT_URL`: URL, с которым будет производиться операция. Значение этого параметра также может быть задано в вызове функции curl_init().

- `CURLOPT_USERPWD`: Стока с именем пользователя и паролем в виде [username]:[password].

- `CURLOPT_PROXYUSERPWD`: Стока с именем пользователя и паролем к HTTP прокси-серверу в виде [username]:[password].

- `CURLOPT_RANGE`: Задает участок файла, который нужно загрузить, в формате "X-Y" , причем X или Y могут быть опущены. Протокол HTTP также поддерживает передачу нескольких фрагментов файла, это задается в виде "X-Y,N-M".

- `CURLOPT_POSTFIELDS`: Строка, содержащая данные для HTTP POST запроса.

- `CURLOPT_REFERER`: Задает значение HTTP заголовка "Referer: ".

- `CURLOPT_USERAGENT`: Задает значение HTTP заголовка "User-Agent: ".

- `CURLOPT_FTPPORT`: Задает значение, которое будет использоваться для определения IP адреса для команды "PORT" протокола ftp. Команда "PORT" сообщает серверу, с каким IP адресом он должен устанавливать соединение. Это может быть IP адрес, имя хоста, имя сетевого интерфейса (под Unix), или просто '-' для использования IP адреса по умолчанию.

- `CURLOPT_COOKIE`: Содержимое заголовка "Cookie: ", который будет отправлен с HTTP запросом.

- `CURLOPT_SSLCERT`: Имя файла с сертификатом в формате PEM.

- `CURLOPT_SSLCERTPASSWD`: Пароль к файлу сертификата, заданному параметром `CURLOPT_SSLCERT`.

- `CURLOPT_COOKIEFILE`: Имя файла, содержащего данные cookie. Данные могут быть либо в формате Netscape, либо просто HTTP-заголовки.

- `CURLOPT_CUSTOMREQUEST`: Задает специальный метод, который будет использован в HTTP запросе вместо`GET` или `HEAD`. Это используется для отправке запросов `DELETE` или других, редко используемых. Допустимыми зачениями являются `GET`, `POST`, и т.д; не передавайте полный HTTP запрос в этом параметре. Например, 'GET /index.html HTTP/1.0\r\n\r\n' недопустимо.

  > Замечание: Перед использованием этого параметра убедитесь, что сервер, к которому вы обращаетесь, поддерживает требуемый метод.

- `CURLOPT_PROXY`: Имя HTTP прокси, через который будут направляться запросы.

- `CURLOPT_INTERFACE`: Имя используемого сетевого интерфейса. Может быть именем интерфейса, IP адресом или именем хоста.

- `CURLOPT_KRB4LEVEL`: Уровень безопасности KRB4 (Kerberos 4). Допустимы следующие значения (в порядке возрастания безопасности) : 'clear', 'safe', 'confidential', 'private'. Если переданное значение не входит в этот список, используется 'private'. Установка этого параметра в `NULL`, запрещает безопасность KRB4 . В настоящее время безопасность KRB4 поддерживается только для протокола FTP.

- `CURLOPT_HTTPHEADER`: Массив с HTTP заголовками.

- `CURLOPT_QUOTE`: Массив с FTP командами, которые будут выполнены перед выполнением основного запроса.

- `CURLOPT_POSTQUOTE`: Массив с FTP командами, которые будут выполнены после выполнения основного запроса.

Для перечисленных ниже параметров, `value` должен быть дескриптором файла, возвращенным функцией fopen():

- `CURLOPT_FILE`: Файл, в который будет выведен результат операции. По умолчанию STDOUT.

- `CURLOPT_INFILE`: Файл, содержащий данные для передачи.

- `CURLOPT_WRITEHEADER`: Файл, в который будут выведены полученные заголовки.

- `CURLOPT_STDERR`: Файл, в который будут выводиться сообщения об ошибках. По умолчанию STDERR.

`In response to "brett at brettbrewer dot com" and Jamolkhon, the fact you don't take into account is when a redirection (Location: ...) occurs, all the headers are given so the \r\n\r\n can also separate twp consecutive headers.
An even better trick to get the header is to use CURLINFO_HEADER_SIZE :
$header_size = curl_getinfo($ch, CURLINFO_HEADER_SIZE);
$headers = substr($output, 0, $header_size - 4);
$body = substr($output, $header_size);
Then $headers contains all the headers.`

`If you are trying to use CURLOPT_FOLLOWLOCATION and you get this warning:
Warning: curl_setopt() [function.curl-setopt]: CURLOPT_FOLLOWLOCATION cannot be activated when in safe_mode or an open_basedir is set...
then you will want to read http://www.php.net/ChangeLog-4.php which says "Disabled CURLOPT_FOLLOWLOCATION in curl when open_basedir or safe_mode are enabled." as of PHP 4.4.4/5.1.5. This is due to the fact that curl is not part of PHP and doesn't know the values of open_basedir or safe_mode, so you could comprimise your webserver operating in safe_mode by redirecting (using header('Location: ...')) to "file://" urls, which curl would have gladly retrieved.
Until the curl extension is changed in PHP or curl (if it ever will) to deal with "Location:" headers, here is a far from perfect remake of the curl_exec function that I am using.
Since there's no curl_getopt function equivalent, you'll have to tweak the function to make it work for your specific use. As it is here, it returns the body of the response and not the header. It also doesn't deal with redirection urls with username and passwords in them.
<?php

}
curl_setopt($ch, CURLOPT_HEADER, true);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$data = curl_exec($ch);
list($header, $data) = explode("\n\n", $data, 2);
$http_code = curl_getinfo($ch, CURLINFO_HTTP_CODE);
if ($http_code == 301 || $http_code == 302)
{
$matches = array();

//couldn't process the url to redirect to

`I have seen two posts complaining the "CURLOPT_POSTFIELDS" option is not working well.
This was the solution given below:
$o="";
foreach ($post_data as $k=>$v)
{
$o.= "$k=".utf8_encode($v)."&";
}
$post_data=substr($o,0,-1);
The assumption that this is an error is not true, as stated on http://curl.rtin.bz/docs/httpscripting.html:
" The data you send to the server MUST already be properly encoded, curl will
not do that for you. For example, if you want the data to contain a space,
you need to replace that space with %20 etc. Failing to comply with this
will most likely cause your data to be received wrongly and messed up."
This means you do really have to encode the data yourself the right way.`

`As Yevgen mentioned earlier sometimes we can't use CURLOPT_COOKIEJAR and CURLOPT_COOKIEFILE. Below is a header callback function I wrote back in January that lets you maintain cookies between cURL requests. Cookies are added to $ch during all requests even during redirection, so you can use it together with CURLOPT_FOLLOWLOCATION.
Here is the code:
function read_header($ch, $string)
{
global $location; #keep track of location/redirects
global $cookiearr; #store cookies here
global $ch;
# ^overrides the function param $ch
# this is okay because we need to
# update the global $ch with
# new cookies
$length = strlen($string);
if(!strncmp($string, "Location:", 9))
{ #keep track of last redirect
$location = trim(substr($string, 9, -1));
}
if(!strncmp($string, "Set-Cookie:", 11))
{ #get the cookie
$cookiestr = trim(substr($string, 11, -1));
$cookie = explode(';', $cookiestr);
$cookie = explode('=', $cookie[0]);
$cookiename = trim(array_shift($cookie));
$cookiearr[$cookiename] = trim(implode('=', $cookie));
}
$cookie = "";
if(trim($string) == "")
{ #execute only at end of header
foreach ($cookiearr as $key=>$value)
{
$cookie .= "$key=$value; ";
}
curl_setopt($ch, CURLOPT_COOKIE, $cookie);
}
return $length;
}
Using the header function with curl (add this before curl_exec):
#don't forget globals, especially if you are using this in function
curl_setopt($ch, CURLOPT_HEADERFUNCTION, 'read_header');
This code assumes that you will reuse $ch without initializing it every time (call curl_init only once, in the beginning). If you need to initialize $ch again at any point in your code you can access the currently stored cookies in $cookiearr and include them in the new $ch.
I wrote this function before I had enough experience with regular expressions so you won't find any preg_match calls here. I have used this code for quite a while and without any problems accessing gmail, yahoo, hotmail, aol etc. where I had to go through login and a few pages before getting to what I was looking for.

`Note that if you want to use a proxy and use it as a _cache_, you'll have to do:
curl_setopt($ch, CURLOPT_HTTPHEADER, array("Pragma: "));
else by default Curl puts a "Pragma: no-cache" header in and thus force cache misses for all requests.`

`You can use CURLOPT_HEADERFUNCTION with a callback inside an object. This makes is it easy to capture the headers for later use. For example:
<?
class Test
{
public $headers;
//...
public function exec($opts)
{
$this->headers = array();
$opts[CURLOPT_HEADERFUNCTION] = array($this, '_setHeader');
$ch = curl_init();
curl_setopt_array($ch, $opts);
return curl_exec($ch);
}
private function _setHeader($ch, $header)
{
$this->headers[] = $header;
return strlen($header);
}
}
$test = new Test();
$opts = array(
//... your curl opts here
);
$data = $test->exec($opts);
print_r($test->headers);
?>
...something like that
(This works in php v. 5.1.4)`

`Clarification on the callback methods:
- CURLOPT_HEADERFUNCTION is for handling header lines received *in the response*,
- CURLOPT_WRITEFUNCTION is for handling data received *from the response*,
- CURLOPT_READFUNCTION is for handling data passed along *in the request*.
The callback "string" can be any callable function, that includes the array(&$obj, 'someMethodName') format.

`Sometimes you can't use CURLOPT_COOKIEJAR and CURLOPT_COOKIEFILE becoz of the server php-settings(They say u may grab any files from server using these options). Here is the solution
1)Don't use CURLOPT_FOLLOWLOCATION
2)Use curl_setopt($ch, CURLOPT_HEADER, 1)
3)Grab from the header cookies like this:
preg_match_all('|Set-Cookie: (.*);|U', $content, $results);
$cookies = implode(';', $results[1]);
4)Set them using curl_setopt($ch, CURLOPT_COOKIE, $cookies);

`- CURLOPT-HTTPAUTH is defined in php 4.4.2 9and maybe lower), even tough the manual says php 5.0 only...
- it is not clear from the manual what kind of http auth is carried out by default if user specifies username/pwd: it is BASIC auth

`To further expand upon use of CURLOPT_CAPATH and CURLOPT_CAINFO...
In my case I wanted to prevent curl from talking to any HTTPS server except my own using a self signed certificate. To do this, you'll need openssl installed and access to the HTTPS Server Certificate (server.crt by default on apache)
You can then use a command simiar to this to translate your apache certificate into one that curl likes.
$ openssl x509 -in server.crt -out outcert.pem -text
Then set CURLOPT_CAINFO equal to the the full path to outcert.pem and turn on CURLOPT_SSL_VERIFYPEER.
If you want to use the CURLOPT_CAPATH option, you should create a directory for all the valid certificates you have created, then use the c_rehash script that is included with openssl to "prepare" the directory.
If you dont use the c_rehash utility, curl will ignore any file in the directory you set.`

The solution is to encode in a unique string all the post key=>values
Possibly this code doesnt work:

`AZAds is a traffic exchange that we wrote. We wanted to come up with a way to check the UP or DOWN status of a submitted URL. Here is the solution we came up with. Can also be used for a site monitoring service.
<?
$uServer="$url";
@$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "$uServer");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_HEADER, 0);
@curl_exec($ch);
$errnum=curl_errno($ch);
@curl_close($ch);
if($errnum != "0") {
print "Remote Site Status: DOWN";
} else {
print "Remote Site Status: UP";
}
?>
Simply feed the URL to be tested into $url. The code will check the site and return the error code if there is one and display to appropriate message.
Hope this is useful.

`Hi!
I have found some information I am sure it could help lot of programmers when they want to connect with curl to any https website and they haven't a good or right CA Cert :)
I give you just one example It has resolved me 2 hours of my time looking for a solution.
It is simple, just if you get any error in the curl_exec (use curl_error(...) to see the error to trace it) add the next line and everything is solved:
(note: replace $ch with the right curl variable)
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
<?php
$ch = curl_init();
$res= curl_setopt ($ch, CURLOPT_URL,"https://yoururl/cgi");
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
curl_setopt ($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, "Idc=si&");
curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1);
$xyz = curl_exec ($ch);
curl_close ($ch);
echo $xyz;
if ($xyz == NULL) {
echo "Error:<br>";
echo curl_errno($ch) . " - " . curl_error($ch) . "<br>";
}
?>
I hope this helps.

`If you specify a CAINFO, note that the file must be in PEM format! (If not, it won't work).
Using Openssl you can use:
openssl x509 -in <cert> -inform d -outform PEM -out cert.pem
To create a pem formatted certificate from a binary certificate (the one you get if you download the ca somewhere).`

`I found it very annoying that cURL did not offer any easy way to extract the response headers. If you do
curl_setopt($ch, CURLOPT_HEADER, 1);
then you only get the headers output inline with the rest of your response. Here's a nice little function to parse the cURL response when you use CURLOPT_HEADER. I took it from an example on another site and turned it into a function. It assumes you're using CURLOPT_RETURNTRANSFER to return the response to some variable that is then passed to the function. You just pass it a curl_exec result and it returns the result parsed into an array with headers broken up into their correct parts.

`A bit more documentation (without minimum version numbers):
- CURLOPT_WRITEFUNCTION
- CURLOPT_HEADERFUNCTION
Pass a function which will be called to write data or headers respectively. The callback function prototype:
long write_callback (resource ch, string data)
The ch argument is CURL session handle. The data argument is data received. Note that its size is variable. When writing data, as much data as possible will be returned in all invokes. When writing headers, exactly one complete header line is returned for better parsing.
The function must return number of bytes actually taken care of. If that amount differs from the amount passed to this function, an error will occur.
- CURLOPT_READFUNCTION
Pass a function which will be called to read data. The callback function prototype:
string read_callback (resource ch, resource fd, long length)
The ch argument is CURL session handle. The fd argument is file descriptor passed to CURL by CURLOPT_INFILE option. The length argument is maximum length which can be returned.
The function must return string containing the data which were read. If length of the data is more than maximum length, it will be truncated to maximum length. Returning anything else than a string means an EOF.
[Note: there is more callbacks implemented in current cURL library but they aren't unfortunately implemented in php curl interface yet.]`

`About the CURLOPT_HTTPHEADER option, it took me some time to figure out how to format the so-called 'Array'. It fact, it is a list of strings. If Curl was already defining a header item, yours will replace it. Here is an example to change the Content Type in a POST:
curl_setopt ($ch, CURLOPT_HTTPHEADER, Array("Content-Type: text/xml"));

`beware that not all cURLlib constants are supported under php :
e.g. CURLOPT_PROGRESSFUNCTION or CURLOPT_WRITEDATA are not supported.
CURLOPT_WRITEFUNCTION, although undocumented is supported. It takes the name of a user_defined function.
the function should take two arguments (the curl handle, and the inputdata) and return the length of the written data
e.g.
function myPoorProgressFunc($ch,$str){
global $fd;
$len = fwrite($fd,$str);
print("#");
return $len;
}
curl_setopt($ch,CURLOPT_WRITEFUNCTION,"myPoorProgressFunc");
Also be aware that CURLOPT_WRITEFUNCTION does NOT take the CURLOPT_FILE as a parameter!
in curl lib it would take CURLOPT_WRITEDATA but this is not supported by php; that's why I use "global $fd;" in my exemple function.
CURLOPT_HEADERFUNCTION works the same, and is guaranteed to receive complete header lines as input!
Hope this helps

`note: if your option comes from a variable eg:
$option = "CURLOPT_RETURNTRANSFER";
$value = "1";
this will fail:

because the curl option is a constant.
use the function constant() to get the value:

`CURLOPT_HTTPHEADER is NOT like the -H command line switch. The command line switch adds or replaces headers (much like the header() line in PHP, but for HTTP clients instead of servers), but the curl extension will eliminate the headers cURL sends by default.
For instance, your Authorization, Host, Referer, Pragma, and Accept headers which are normally written by default or by other CURLOPT_*'s.
Also, it might seem intuitive that this should accept an array hash of header->values, but this is not the case. It accepts an array of strings of the format "Header: Value", much like the -H command-line switch.
Hope this helps,

`It's possible to take advantage of multiple URLs on the same host in one curl_exec transaction ... just use multiple instances of CURLOPT_URL.
Example:
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "http://foo.com/a.html");
curl_setopt($ch, CURLOPT_URL, "http://foo.com/b.html");
curl_setopt($ch, CURLOPT_URL, "http://foo.com/c.html");
curl_exec($ch);
curl_close($ch);
... the URLs appear to be hit in the same order they are entered. This takes advantage of cURL's Persistant Connection capability if all the URLs are on the same host!`
