Answer 1

在您的 php 配置中禁用 magic_quotes，然后编辑所有出现此错误的文本以进行更正。

Answer 2

更改 php.ini 设置magic_quotes_gpc = Off。如果您不能这样做，请ini_set在 php 代码本身中使用。如果您不能这样做，请使用您获得stripslashes的价值。$_POST

Answer 3

我同意@Lee 的说法，但是如果你需要通过正则表达式来做到这一点。这应该这样做。

<?php
    $pattern = '/\\\"/';
    $replacement =  '';
    $subject = '<img scr="\"http://test.in/public/admin/uploadfiles/Lighthouse(2).jpg\"">';
    $result = preg_replace ($pattern, $replacement, $subject);
?> 

Answer 4

使用正则表达式，您可以执行以下操作：要删除第一个 \"，请使用

preg_replace('/<img scr=\"\\\/', '<img scr=', $your_string); 

然后将第二部分替换为

preg_replace('/\\\\"\">/', '">', $your_string);
