Sometimes for some reason is happens that PHP or Javascript or some naughty insert a lot of backslash. Ordinary function does not notice that. Therefore, it is necessary that the bit "inflate":
<?php
function removeslashes($string)
{
$string=implode("",explode("\\",$string));
return stripslashes(trim($string));
}
/* Example */
$text="My dog don\\\\\\\\\\\\\\\\'t like the postman!";
echo removeslashes($text);
?>
RESULT: My dog don't like the postman!
This flick has served me wery well, because I had this problem before.| CARVIEW |

PHP: stripslashes - Manual
stripslashes
(PHP 4, PHP 5, PHP 7, PHP 8)
stripslashes — Un-quotes a quoted string
Description
Un-quotes a quoted string.
stripslashes() can be used if you aren't inserting this data into a place (such as a database) that requires escaping. For example, if you're simply outputting data straight from an HTML form.
Parameters
string-
The input string.
Return Values
Returns a string with backslashes stripped off.
(\' becomes ' and so on.)
Double backslashes (\\) are made into a single
backslash (\).
Examples
Example #1 A stripslashes() example
<?php
$str = "Is your name O\'reilly?";
// Outputs: Is your name O'reilly?
echo stripslashes($str);
?>Note:
stripslashes() is not recursive. If you want to apply this function to a multi-dimensional array, you need to use a recursive function.
Example #2 Using stripslashes() on an array
<?php
function stripslashes_deep($value)
{
$value = is_array($value) ?
array_map('stripslashes_deep', $value) :
stripslashes($value);
return $value;
}
// Example
$array = array("f\\'oo", "b\\'ar", array("fo\\'o", "b\\'ar"));
$array = stripslashes_deep($array);
// Output
print_r($array);
?>The above example will output:
Array
(
[0] => f'oo
[1] => b'ar
[2] => Array
(
[0] => fo'o
[1] => b'ar
)
)

Hi,
Here are recursive addslashes / stripslashes functions.
given a string - it will simply add / strip slashes
given an array - it will recursively add / strip slashes from the array and all of it subarrays.
if the value is not a string or array - it will remain unmodified!
<?php
function add_slashes_recursive( $variable )
{
if ( is_string( $variable ) )
return addslashes( $variable ) ;
elseif ( is_array( $variable ) )
foreach( $variable as $i => $value )
$variable[ $i ] = add_slashes_recursive( $value ) ;
return $variable ;
}
function strip_slashes_recursive( $variable )
{
if ( is_string( $variable ) )
return stripslashes( $variable ) ;
if ( is_array( $variable ) )
foreach( $variable as $i => $value )
$variable[ $i ] = strip_slashes_recursive( $value ) ;
return $variable ;
}
?>

A replacement that should be safe on utf-8 strings.
<?php
preg_replace(array('/\x5C(?!\x5C)/u', '/\x5C\x5C/u'), array('','\\'), $s);
?>

If you need to remove all slashes from a string, here's a quick hack:
<?php
function stripallslashes($string) {
while(strchr($string,'\\')) {
$string = stripslashes($string);
}
}
?>
Hope it's usefull , O-Zone

in response to crab dot crab at gmail dot com:
$value need not be passed by reference. The 'stripped' value is returned. The passed value is not altered.

Might I warn readers that they should be vary careful with the use of stripslashes on Japanese text. The shift_jis character set includes a number of two-byte code charcters that contain the hex-value 0x5c (backslash) which will get stripped by this function thus garbling those characters.
What a nightmare!
