Описание
string stripslashes
( string $str
)
Удаляет экранирующие бэкслэши. (\' преобразуется в ', и т.д.). Двойные бэкслэши (\\) преобразуется в одиночные(\).
stripslashes() используется, например, когда директива конфигурации magic_quotes_gpc включена (она включена по умолчанию), и экранирование символов не требуется. Например, данные не вставляются в базу данных, а просто выводятся в браузер.
Пример #1 Пример использования stripslashes()
<?php
$str = "Is your name O\'reilly?";
// выводит: Is your name O'reilly?
echo stripslashes($str);
?>

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!
in response to crab dot crab at gmail dot com:
$value need not be passed by reference. The 'stripped' value is returned. The passed value is not altered.
If you need to remove all slashes from a string, here's a quick hack:
<?php
function stripallslashes($string) {
while(strchr($string,'\\')) {
$string = stripslashes($string);
}
}
?>
Hope it's usefull , O-Zone
A replacement that should be safe on utf-8 strings.<?php
preg_replace(array('/\x5C(?!\x5C)/u', '/\x5C\x5C/u'), array('','\\'), $s);
?>
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 $variable ;
}
?>
Sometimes for some reason is happens that PHP or Javascript or some naughty insert a lot of backslash. Ordinary function does not notice that. Therefore, it is necessary that the bit "inflate":
<?php
function removeslashes($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.
