emai正则
这样写怎么匹配不了邮件
function check($str){
$re='/([a-z0-9_-]+)@\1(\.[a-z0-9_-])+/i';
preg_match($re,$str,$result);
return $result;
}
var_dump(check('123456@qq.com'));
?>
------最佳解决方案--------------------
按照你的正则方式,邮箱改成123456@123456.com就能匹配到了。
------其他解决方案--------------------
你的@后面的\1是后向引用啊当然会出问题
$re='/([a-z0-9_-]+)@([a-z0-9_-]+)(\.([a-z0-9_-])+)+/i';
------其他解决方案--------------------
