[导读]：PHP 邮箱正则表达式代码如下： /^[_a-z0-9-]+(\.[_a-z0-9-]+)*@[a-z0-9-]+(\.[a-z0-9-]+)*(\.[a-z]{2,})$/ 实例 ?php $mail = ' runoob@runoob.com ' ; // 邮箱地址 $pattern = /^[_a-z0-9-]+(\.[_a-z0-9-]+)*@[a-z0-9-]+(\.[a-z...
PHP 邮箱正则表达式代码如下：
/^[_a-z0-9-]+(\.[_a-z0-9-]+)*@[a-z0-9-]+(\.[a-z0-9-]+)*(\.[a-z]{2,})$/
实例
$mail = 'runoob@runoob.com'; //邮箱地址 $pattern = "/^[_a-z0-9-]+(\.[_a-z0-9-]+)*@[a-z0-9-]+(\.[a-z0-9-]+)*(\.[a-z]{2,})$/"; preg_match($pattern, $mail, $matches); var_dump($matches); //输出匹配结果以上代码运行输出结果为：
array(4) {
[0]=>
string(17) "runoob@runoob.com"
[1]=>
string(0) ""
[2]=>
string(0) ""
[3]=>
string(4) ".com"
}
使用 FILTER_VALIDATE_EMAIL 过滤器
实例
$email = 'runoob@runoob.com'; //邮箱地址 if (filter_var($email, FILTER_VALIDATE_EMAIL)) { $emailMsg = "正确邮箱格式"; } else { $emailMsg = "非法邮箱格式"; } echo $emailMsg;本文来自投稿，不代表微盟圈立场，如若转载，请注明出处：https://www.vm7.com/a/ziyuan/111592.html
