推荐答案

我认为您不是在寻找正则表达式，而是在寻找 stripslashes($str) 方法.

I think you aren't looking for a regex, but for the stripslashes($str) method.

从评论中，我明白你只会用任何东西替换 \"，你应该在这里使用一个简单的 str_replace，正如@Gumbo 所说:>

From the comments, I understand that you will only replace \" with nothing, you should use a simple str_replace here, as @Gumbo said:

$str = ...;
$newStr = str_replace('\"', '', $str);

echo $newStr;

您可以为此使用正则表达式，但 pReg 库并不快，如果您能找到执行相同操作的 str_* 或数组变体，我总是建议使用它而不是 preg_*

You can use regular expressions for this, but the pReg library isn't fast, if you can find a str_* or array variant which does the same I always recommend to use that instead of preg_*
