问题描述

因此，我在邮件脚本中使用了eregi，但是最近，我收到了该功能已过时的错误消息.

So, i was using eregi in my mail script, but as of lately, i get the error that the function is deprecated.

因此，替换以下代码的最简单方法是:

So, what is the easiest way to replace the following bit of code:

if (!eregi("^[A-Z0-9._%-]+@[A-Z0-9._%-]+\.[A-Z]{2,4}$", trim($_POST['email'])))?

推荐答案

 if (!preg_match("/^[A-Z0-9.%-]+@[A-Z0-9.%-]+.[A-Z]{2,4}$/", trim($_POST['email'])))

使用preg_match.

Using preg_match.

因为ereg_ *函数已在PHP> = 5.3中弃用

Because ereg_* functions is deprecated in PHP >= 5.3

为了更好地进行电子邮件验证，还使用了 filter_var

Also for email validation better used filter_var

if (!filter_var(trim($_POST['email']), FILTER_VALIDATE_EMAIL))
    echo 'Email is incorrect';
