How to remove backslash from escaped characters in php

本教程操作环境:windows7系统、PHP5.6版,DELL G3电脑。

php去除转义字符中的反斜杠的方法:

addslashes函数主要是在字符串中添加反斜杠对特殊字符进行转义,stripslashes则是去掉转义后字符串中的反斜杠\,比如当你提交一段json数据到PHP端的时候可能会遇到json字符串中有\导致json_decode函数无法将json数据转换成数组的情况,这时你就需要stripslashes函数。

该函数用于清理从数据库或 HTML 表单中取回的数据。

<?php
function delete_fxg(&$array) {
         while(list($k,$v) = each($array)) {
               if (is_string($v)) {
                   $array[$k] = stripslashes($v);//去掉反斜杠字符
               }
               if (is_array($v))  {
                   $array[$k] = delete_fxg($v);//调用本身,递归作用
              }
        }
        return $array;
}
$str[0][1]="123123\\\\";
$str[0][2]="456456\\\\";
delete_fxg($str);
print_r($str);
?>
