# fgetcsv

(PHP 3 >= 3.0.8, PHP 4, PHP 5)

fgetcsv -- Читает строку из файла и производит разбор данных CSV

## Описание

array fgetcsv ( resource handle [, int length [, string delimiter [, string enclosure]]] )

`handle`

  Корректный файловый указатель на файл, успешно открытый при помощи fopen(), popen(), или fsockopen().

`length` (Необязательный)

  Должен быть больше самой длинной строки (в символах), найденной в CSV-файле (включая завершающий символ конца строки). Он стал необязательным в PHP 5. Если этот аргумент не указан (или равен 0 в версиях PHP 5.0.4 и выше), максимальная длинна строки не ограничена, но функция работает немного медленнее.

`delimiter` (Необязательный)

  Устанавливает разделитель поля (только один символ). По умолчанию это запятая.

`enclosure` (Необязательный)

  Устанавливает символ ограничителя поля (только один символ). По умолчанию это двойная кавычка. Добавлен в PHP 4.3.0.

Данная функция похожа на функцию fgets(), с той разницей, что она производит анализ строки на наличие записей в формате CSV и возвращает найденные поля в качестве массива.

Функция fgetcsv() возвращает `FALSE` в случае ошибки, а также по достижению конца файла.

> Замечание: Пустая строка CSV-файла будет возвращена в качестве массива, содержащего единственный элемент null, ошибки в данном случае не возникнет.

Пример 1. Чтение и вывод на экран содержания CSV-файла

`<?php
$row = 1;
$handle = fopen("test.csv", "r");
while (($data = fgetcsv($handle, 1000, ",")) !== FALSE) {
$num = count($data);
echo "<p> $num полей в строке $row: <br /></p>\n";
$row++;
for ($c=0; $c < $num; $c++) {
echo $data[$c] . "<br />\n";
}
}
fclose($handle);
?>`

fgetcsv() стала правильно обрабатывать двоичные данные начиная с версии PHP 4.3.5

> Замечание: Эта функция принимает во внимание настройки локали. К примеру, если `LANG` установлен в `en_US.UTF-8`, то файлы в однобайтовой кодировке будут неправильно прочитаны этой функцией.

> Замечание: Если у вас возникают проблемы с распознаванием `PHP` окончания строк при чтении файлов на Macintosh-совместимом компьютере или при чтении файлов, созданных на Macintosh-совместимом компьютере, необходимо включить опцию auto_detect_line_endings.

`Whenever you have to parse CSV data that isn't stored in a file, or should you need to encode your data as CSV, you may use my set of functions, featuring:
- bi-directional conversion, meaning you may read as well as write CSV data, to or from your arrays.
- Support for customizable field separator, newline character (also auto-detects and converts Win/Mac/*nix newlines).
- separators, newlines (auto-converted), properly handled within fields enclosed in quotation marks. Last line may or may not be terminated by a newline.
- checks for possibly corrupt data (whenever last field in last row starts, but is not terminated, with a quotation mark).
- Top speed guaranteed by use of strpos(), substr() etc.; room yet for some optimization (especially with associative arrays).
- Clean (no data stored or retrieved from outside function scope, except for CSVstruct array).
Requires PHP 4.3 or newer.
Enjoy!

`If you need to import a huge CSV file into a database, use the bulk insert technique instead of many line-by-line inserts:
- MSSQL: bcp tool and "BULK INSERT" SQL
- MySQL: mysqlimport tool and "LOAD DATA INFILE" SQL

-------------------------------------

$data = $importer->get();
print_r($data);
Sample usage for large files:-
-------------------------------------
$importer = new CsvImporter("large.txt",true);

`Should you need it, here is a nice and simple function for escaping csv fields properly.
This version is conditional - it only adds quotes if needed:
<?
function csv_escape($str) {
$str = str_replace(array('"', ',', "\n", "\r"), array('""', ',', "\n", "\r"), $str, &$count);
if($count) {
return '"' . $str . '"';
} else {
return $str;

This version is even simpler, but adds quotes even if not needed.

`Thank you donnoman and ramdac, that's exactly the kind of function I needed!
For my use, assigning metadata to images, I actually want the first dimension array key to be a string pulled from the CSV; the unique filename, instead of a number.
Easy, just insert the second dim's key...
Change: $return[]=$row;
To: $return[$data[0]]=$row;
(You may indeed wish to confirm unique values first!)
Also, if you find the fields getting out of sync, increase the $len byte count for the largest cell of data.`

`Note that fgetcsv() uses the system locale setting to make assumptions about character encoding.
So if you are trying to process a UTF-8 CSV file on an EUC-JP server (for example),
you will need to do something like this before you call fgetcsv():
setlocale(LC_ALL, 'ja_JP.UTF8');
[Also not that setlocale() doesn't *permanently* affect the system locale setting]`

`I was using the function to import a csv file that had some values with "\" included this confused the import function to ignore the End of line and hence an incorrect number of rows is returned to me.
Suggest you try to replace that \ and { brackets as well since they have the same function of an escape character before u import the function

`beware of characters of binary value == 0, as they seem to make fgetcsv ignore the remaining part of a line where they appear.
Maybe this is normal under some convention I don't know, but a file exported from Excel had those as values for some cells *sometimes*, thus fgetcsv return variable cell counts for different lines.

`Based on my observations a few comments below I have written a class that incorporates all these features. Here is the class description:
----------
This class will parse a csv file in either standard or MS Excel format.
Two methods are provided to either process a line at a time or return the whole csv file as an array.
It can deal with:
- Line breaks within quoted fields
- Character seperator (usually a comma or semicolon) in quoted fields
- Can leave or remove leading and trailing spaces or tabs
- Can leave or skip empty rows.
- Windows and Unix line breaks dealt with automatically. (Care must be taken with Macintosh format.)
Also, the escape character is automatically removed.
-----------
So basically it should "just work". If it doesn't please send me an email ;-)
You can download it from: http://www.phpclasses.org/browse/package/2672.html
An example on how to use the class and a test.csv file are also provided.`

`Newer PHP versions handle cvs files slightly different than older versions.
"Max Mustermann"|"Muster Road 34b"|"Berlin" |"Germany"
"Sophie Master" |"Riverstreet" |"Washington"|"USA"
The extra spaces behind a few fields in the example (which are useful, when you manually manage a small csv database to align the columns) were ignored by fgetcsv from PHP 4.3. With the new 4.4.1 release they get appended to the string, so you end up with "Riverstreet " instead the expected "Riverstreet".
Easy workaround is to just trim all fields after reading them in.
while ( $data = fgetcsv($database, 32768, "|") )
{
$i = 0;
while(isset($data[$i]))
{
$data[$i] = rtrim($data[$i]);

`The fgetcsv function seems to follow the MS excel conventions, which means:
- The quoting character is escaped by itself and not the back slash.
(i.e.Let's use the double quote (") as the quoting character:
Two double quotes "" will give a single " once parsed, if they are inside a quoted field (otherwise neither of them will be removed).
\" will give \" whether it is in a quoted field or not (same for \\) , and
if a single double quote is inside a quoted field it will be removed. If it is not inside a quoted field it will stay).
- leading and trailing spaces (\s or \t) are never removed, regardless of whether they are in quoted fields or not.
- Line breaks within fields are dealt with correctly if they are in quoted fields. (So previous comments stating the opposite are wrong, unless they are using a different PHP version.... I am using 4.4.0.)
So fgetcsv if actually very complete and can deal with every possible situation. (It does need help for macintosh line breaks though, as mentioned in the help files.)
I wish I knew all this from the start. From my own benchmarks fgetcsv strikes a very good compromise between memory consumption and speed.
-------------------------
Note: If back slashes are used to escape quotes they can easily be removed afterwards. Same for leading and trailing spaces.`

`"marc at henklein dot com" posted a cool function "CSV2Array", but there's an error. If the last char of the CSV file isn't a carriage return, the function can't take the last field of the last line in the CSV.

this code:

to:
if ($i+1 < strlen($line) && $line[$i+1] == '"') {
The reason is that if the quote (") is at the last line of the string, then it will try to reach an undefined space in the string, therefore giving a PHP error.
Of course his function is great if your line is a true compatible csv line, but I leave that to you to judge if you can do this assumption ;-)`

`using the example above with a length of 1000 will truncate any csv rows longer than 1000 bytes, the remainder of that line will be represented next time you call $data = fgetcsv(). one solution i have seen to this is to use filesize("test.csv") as the length argument, however sometimes with large csv files you may encounter errors for exceeding the memory limit. to remedy this, i have read the csv file into an array, looping through that array to find the longest line in the csv, and then using that value as my length argument, unset($array) to free up the memory. im open to better solutions.

`For all those people struggling with Macintosh conversions, since PHP 4.3 there is a new runtime setting available:
auto_detect_line_endings boolean
When turned on, PHP will examine the data read by fgets() and file() to see if it is using Unix, MS-Dos or Macintosh line-ending conventions.
This enables PHP to interoperate with Macintosh systems, but defaults to Off, as there is a very small performance penalty when detecting the EOL conventions for the first line, and also because people using carriage-returns as item separators under Unix systems would experience non-backwards-compatible behaviour.`

`beware of using this function in two different php versions,
in php 4.3 the 4th parameter can be given altough empty
in php 4.2 you get just a warning but it is not able to read the csv file if you place an enclosure that is empty`

`If anyone else is taking on the task of converting from FileMaker Pro to MySQL, you might find this useful:
Here's a collection of simple functions that take a CSV file, re-formats the data and writes to a file with MySQL INSERTs.
ORIGINAL DATA:
"1", "foo", "2"
"3", "bar", "4"
OUTPUT
INSERT info mysql_table VALUES('', '1', 'foo', '2');
INSERT info mysql_table VALUES('', '3', 'bar', '4');
For simple data it works alright, but I could not find a way to escape the contents before assembling the INSERT statements - kept getting "bad argument for implode()"...

`You should pay attention to the fact that "fgetcsv" does remove leading TAB-chars "chr(9)" while reading the file.
This means if you have a chr(9) as the first char in the file and you use fgetcsv this char is automaticaly deleted.
Example:
file content:
chr(9)first#second#third#fourth
source:
$line = fgetcsv($handle,500,"#");
The array $line looks like:
$line[0] = first
$line[1] = second
$line[2] = third
$line[3] = fourth
and not
$line[0] = chr(9)first
$line[1] = second
$line[2] = third
$line[3] = fourth
All chr(9) after another char is not deleted!
Example:
file content:
Achr(9)first#second#third#fourth
source:
$line = fgetcsv($handle,500,"#");
The array $line looks like:
$line[0] = Achr(9)first
$line[1] = second
$line[2] = third
$line[3] = fourth`

`For those of you having problems with Excel's version of CSV file exports (which include the infamous ^M characters in *NIX editors, such as VIM) here is a simple script to remove them and replace them in the normal UNIX newline character (\n).
<?
$fp = fopen('/dev/stdin','r');
while(!feof($fp)){
$line = chop(fgets($fp,4096));
$ret = ereg_replace(chr(13) . chr(10),"\n",$line);

Usage: cat file_with_windows_newlines | php -q strip_newlines.php > outfile
(this works for other stuff too, like PHP "coders" who use Notepad and upload to a UNIX environment).`

`fgetcsv stops reading your file?
I had to write a script to validate and import a large amount of data to MySQL and it would stop running. I've noticed, after trawling the internet for a solution, quite a few people have had similar problems.
Solution? Like a dope I had forgotten to put in
set_time_limit()
within a loop. Otherwise the script would time out before it finished importing all the data.
Moral of the story? Only suppress errors after your script works with a large amount of test data!`

`This function takes a csv line and splits it into an array, much like fgetcsv does but you can use it on data that isn't coming in from a file, or you can read data from a file some other way (like if your Mac files aren't being read correctly) and use this to split it. If you have any corrections, comments (good or bad), etc. I would appreciate an email to the above address.

`If you're working in Excel on a Mac and are exporting a spreadsheet as a CSV, PHP won't recognise the line breaks, and interprets the file as one really long line. It borders on a bug really. For me, I just open the file in BBEdit or BBEdit Lite, convert the file from Mac to Unix, and all is well. But if you're dealing with user-contributed files, you'll need to convert the line-endings first... replacing all \r's with \n's should do it.`

`Quoting csv is pretty simple, and there are two steps..I note in previous comments only the second step has been explained.
First fields with double quotes need to double up the quotes, ie _He said "Timmy"..._ should become _He said ""Timmy""..._
Secondly as mentioned above, fields with commas need double quotes.
Here is a simple function to achieve this, that I pass to array walk, if you want to use it somewhere else, prob get rid of reference and return the value.
function check_csv_field_ref(&$item) {
$item = str_replace('"', '""', $item);
if (strpos($item, ",") !== FALSE) {
$item = '"' . $item . '"';
