PHP去掉反斜杠函数:stripslashes()

stripslashes — 反引用一个引用字符串

说明

string stripslashes ( string $str )

反引用一个引用字符串。

 

Note:

如果 magic_quotes_sybase 项开启,反斜线将被去除,但是两个反斜线将会被替换成一个。

 

一个使用范例是使用 PHP 检测 magic_quotes_gpc 配置项的 开启情况(在 PHP 5.4之 前默认是开启的)并且你不需要将数据插入到一个需要转义的位置(例如数据库)。例如,你只是简单地将表单数据直接输出。

参数

str 输入字符串。

 

返回值

返回一个去除转义反斜线后的字符串(\' 转换为 ' 等等)。双反斜线(\\)被转换为单个反斜线(\)。

 

示例一:

<?php
$str  =  "Is your name O\&#39;reilly?" ;
// 输出: Is your name O&#39;reilly?
echo  stripslashes ( $str );

 

Note:

stripslashes() 是非递归的。如果你想要在多维数组中使用该函数,你需要使用递归函数。

 

示例二:

对数组使用 stripslashes()

<?php
function  stripslashes_deep ( $value )
{
$value  =  is_array ( $value ) ?
array_map ( &#39;stripslashes_deep&#39; ,  $value ) :
stripslashes ( $value );
return  $value ;
}
// 范例
$array  = array( "f\\&#39;oo" ,  "b\\&#39;ar" , array( "fo\\&#39;o" ,  "b\\&#39;ar" ));
$array  =  stripslashes_deep ( $array );
// 输出
 print_r ( $array );
 ?>

 

以上例程会输出:

Array
(
    [0] => f&#39;oo
    [1] => b&#39;ar
    [2] => Array
        (
            [0] => fo&#39;o
            [1] => b&#39;ar
        ))
