php表单习惯用的正则表达式
php表单常用正则表达式，代码如下所示：
functionis_email($str){
//检验email
returnpreg_match("/^\w+([-+.]\w+)*@\w+([-.]\w+)*\.\w+([-.]\w+)*$/",$str);
}
functionis_url($str){
//检验网址
returnpreg_match("/^http:\/\/[A-Za-z0-9]+\.[A-Za-z0-9]+[\/=\?%\-&_~`@[\]\':+!]*([^<>\"])
*$/",$str);
}
functionis_qq($str){
//检验qq
returnpreg_match("/^[1-9]\d{4,8}$/",$str);
}
functionis_zip($str){
//检验邮编
returnpreg_match("/^[1-9]\d{5}$/",$str);
}
functionis_idcard($str){
//检验身份证
returnpreg_match("/^\d{15}(\d{2}[A-Za-z0-9])?$/",$str);
}
functionis_chinese($str){
检验是否是中文
returnereg("^[".chr(0xa1)."-".chr(0xff)."]+$",$str);
}
functionis_english($str){
//检验是否是英文
returnpreg_match("/^[A-Za-z]+$/",$str);
}
functionis_mobile($str){
//检验是否是手机
returnpreg_match("/^((\(\d{3}\))|(\d{3}\-))?13\d{9}$/",$str);
}
functionis_phone($str){
//建云那是否是电话
returnpreg_match("/^((\(\d{3}\))|(\d{3}\-))?(\(0\d{2,3}\)|0\d{2,3}-)?[1-9]\d{6,7}$/",
$str);
}
functionis_safe($str){
return(preg_match("/^(([A-Z]*|[a-z]*|\d*|[-_\~!@#\$%\^&\*\.\(\)\[\]\{\}<>\?\\\/\'\"]*)|.
{0,5})$|\s/",$str)!=0);
}
}
PS：下面再给大家分享一段代码
]+(?:\([\w\d]+\)|([^[:punct:]\s]|\/)))/';
returnRegex::PublicMethod($pattern,$subject);
}
/**
*@URL地址
*/
publicstaticfunctionUrlAddress($subject){
$pattern='/\b(([\w-]+:\/\/?|www[.])[^\s()<>]+(?:\([\w\d]+\)|([^[:punct:]\s]|\/)))/';
returnRegex::PublicMethod($pattern,$subject);
}
/**
*@有效HTTP地址
*/
publicstaticfunctionEffectiveHttp($subject){
$pattern='/\b(([\w-]+:\/\/?|www[.])[^\s()<>]+(?:\([\w\d]+\)|([^[:punct:]\s]|\/)))/';
returnRegex::PublicMethod($pattern,$subject);
}
/**
*@身份证
*/
publicstaticfunctionIdentity($subject){
$pattern='/(^\d{15}$)|(^\d{17}([0-9]|X)$)/';
returnRegex::PublicMethod($pattern,$subject);
}
/**
*@IPv4
*/
publicstaticfunctionIpv4($subject){
$pattern='/^(((\d{1,2})|(1\d{2})|(2[0-4]\d)|(25[0-5]))\.){3}((\d{1,2})|(1\d{2})|(2[0-4]\d)|(25[0-5]))$/';
returnRegex::PublicMethod($pattern,$subject);
}
/**
*@IPv6
*/
publicstaticfunctionIpv6($subject){
$pattern='/^([\da-fA-F]{1,4}:){7}[\da-fA-F]{1,4}$/';
returnRegex::PublicMethod($pattern,$subject);
}
/**
*@匹配正则公共方法
*/
publicstaticfunctionPublicMethod($pattern,$subject){
if(preg_match($pattern,$subject)){
returntrue;
}
returnfalse;
}
}
