本篇文章主要给大家介绍PHP去掉反斜杠的实现方法，那么在PHP中有一个内置函数stripslashes()，其作用就是删除字符串中的反斜杠。下面我们就结合具体的实例，给大家介绍PHP去掉反斜杠的方法，希望对需要的朋友有所帮助！

stripslashes()函数是PHP中的一个内置函数。此函数删除字符串中的反斜杠。

语法:

stripslashes(string)

参数:

该函数只接受一个参数，如上面的语法所示。

说明如下:

string:这是唯一需要的参数，指定函数将在其上操作的字符串。

返回值:

该函数返回一个去掉反斜杠的字符串。

代码示例1：

<?php 
   
    $str = "PHP and\ Python";
echo stripslashes($str);
?>

输出：

PHP and Python

代码示例2：

我们将看到stripslashes()函数的数组实现。stripslashes()不是递归的。为了将这个函数应用于数组，需要一个递归函数。

<?php 
function stripslashes_arr($value)
{
    $value = is_array($value) ?
        array_map(&#39;stripslashes_arr&#39;, $value) :
        stripslashes($value);

    return $value;
}


$array = array("PH\\P ", "an\\d", " \\Java");
$array = stripslashes_arr($array);


print_r($array);
?>

输出：

Array
(
    [0] => PHP
    [1] => and
    [2] =>  Java
)
