maxdb->real_escape_string -- Escapes special characters in a string for use in a SQL statement, taking into account the current charset of the connection

## Description

Procedural style:

string maxdb_real_escape_string ( resource link, string escapestr )

Object oriented style (method):

class maxdb {
string real_escape_sring ( string escapestr )
}

This function is used to create a legal SQL string that you can use in a SQL statement. The string `escapestr` is encoded to an escaped SQL string, taking into account the current character set of the connection.

Characters encoded are `', "`.

## Return values

Returns an escaped string.

## See also

## Example

Пример 1. Object oriented style

`<?php
$maxdb = new maxdb("localhost", "MONA", "RED", "DEMODB");
/* check connection */
if (maxdb_connect_errno()) {
printf("Connect failed: %s\n", maxdb_connect_error());
exit();
}
$maxdb->query("CREATE TABLE temp.mycity LIKE hotel.city");
$city = "'s Hertogenbosch";
/* this query will fail, cause we didn't escape $city */
if (!$maxdb->query("INSERT into temp.mycity VALUES ('11111','$city','NY')")) {
printf("Error: %s\n", $maxdb->sqlstate);
}
$city = $maxdb->real_escape_string($city);
/* this query with escaped $city will work */
if ($maxdb->query("INSERT into temp.mycity VALUES ('22222','$city','NY')")) {
printf("%d Row inserted.\n", $maxdb->affected_rows);
}
$maxdb->close();
?>`

Пример 2. Procedural style

`<?php
$link = maxdb_connect("localhost", "MONA", "RED", "DEMODB");
/* check connection */
if (maxdb_connect_errno()) {
printf("Connect failed: %s\n", maxdb_connect_error());
exit();
}
maxdb_query($link, "CREATE TABLE temp.mycity LIKE hotel.city");
$city = "'s Hertogenbosch";
/* this query will fail, cause we didn't escape $city */
if (!maxdb_query($link, "INSERT into temp.mycity VALUES ('11111','$city','NY')")) {
printf("Error: %s\n", maxdb_sqlstate($link));
}
$city = maxdb_real_escape_string($link, $city);
/* this query with escaped $city will work */
if (maxdb_query($link, "INSERT into temp.mycity VALUES ('22222','$city','NY')")) {
printf("%d Row inserted.\n", maxdb_affected_rows($link));
}
maxdb_close($link);
?>`

The above examples would produce the following output:

    Warning: maxdb_query(): -5016 POS(43) Missing delimiter: ) <...>
    Error: 42000
    1 Row inserted.
