推荐答案

您可以使用preg_replace来执行。

You can use preg_replace to do it.

电子邮件：

$pattern = "/[^@\s]*@[^@\s]*\.[^@\s]*/";
$replacement = "[removed]";
preg_replace($pattern, $replacement, $string);

为网址：

$pattern = "/[a-zA-Z]*[:\/\/]*[A-Za-z0-9\-_]+\.+[A-Za-z0-9\.\/%&=\?\-_]+/i";
$replacement = "[removed]";
preg_replace($pattern, $replacement, $string);
