preg_match 并删除字符

Question

我有一个像

这样的字符串

https:\/\/scontent.xx.fbcdn.net\/hphotos-xta1\/v\/t1.0-9\/p50x50\/11139440_1010664825611559_1305796970308877058_n.jpg?oh=6da07776dd8ba8270c2c32de2957b7d3&oe=560D0AF0

我想用preg_replace函数替换所有的“\” 像这样

https://scontent.xx.fbcdn.net/hphotos-xta1/v/t1.0-9/p50x50/11139440_1010664825611559_1305796970308877058_n.jpg?oh=6da07776dd8ba8270c2c32de2957b7d3&oe=560D0AF0

示例：

• https:// -> https://
• net/hphotos-xta1/ -> net/hphotos-xta1/

我该如何实现？

Answer 1

当 stripslashes() 会为您执行此操作时，为什么要使用其中一个：

结果：

例子

<?php
$string = 'https:\/\/scontent.xx.fbcdn.net\/hphotos-xta1\/v\/t1.0-9\/p50x50\/11139440_1010664825611559_1305796970308877058_n.jpg?oh=6da07776dd8ba8270c2c32de2957b7d3&oe=560D0AF0';

echo stripslashes($string);
