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 = 'codexy@codexy.cn'; //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) "codexy@codexy.cn" [1]=> string(0) "" [2]=> string(0) "" [3]=> string(4) ".com" }
使用 FILTER_VALIDATE_EMAIL 过滤器
实例
$email = 'codexy@codexy.cn'; //邮箱地址
if (!filter_var($email, FILTER_VALIDATE_EMAIL)) {
$emailMsg = "非法邮箱格式";
} else {
$emailMsg = "正确邮箱格式";
}
echo $emailMsg;
