1、电子邮件地址的校验

<&#63;php
/* 校验邮件地址*/
function checkMail($email) {
//用户名,由“\w”格式字符、“-”或“.”组成
$email_name= "\w|(\w[-.\w]*\w)";
//域名中的第一段,规则和用户名类似,不包括点号“.”
$code_at= "@";
$per_domain= "\w|(\w[-\w]*\w)";
//域名中间的部分,至多两段
$mid_domain= "(\." .$per_domain. "){0,2}";
//域名的最后一段,只能为“.com”、“.org”或“.net”
$end_domain= "(\.(com|net|org))";
$rs= preg_match(
"/^{$email_name}@{$per_domain}{$mid_domain}{$end_domain}$/",
$email
);
return (bool)$rs;
}
//测试,下面均返回成功
var_dump( checkMail("root@localhost") );
var_dump( checkMail("Frank.Roulan@esun.edu.org") );
