一个PHP验证Email和IP地址例子，非常的简单好用希望对各位朋友会带来帮助哦。
<script>ec(2);</script>
检查一个用户是否输入了一个有效的email地址，最简单的方法就是使用PHP的内建函数filter_var()，它能够检验email地址。
| 代码如下 | 复制代码 |
|
filter_var('sgamgee@example.com', FILTER_VALIDATE_EMAIL); // Returns "sgamgee@example.com". This is a valid email address. filter_var('sauron@mordor', FILTER_VALIDATE_EMAIL); // Returns boolean false! This is *not* a valid email address. ?> |
