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:
function is_email($str){ //检验email return preg_match("/^\w+([-+.]\w+)*@\w+([-.]\w+)*\.\w+([-.]\w+)*$/", $str); } function is_url($str){ //检验网址 return preg_match("/^http:\/\/[A-Za-z0-9]+\.[A-Za-z0-9]+[\/=\?%\-&_~`@[\]\':+!]*([^<>\"]) *$/", $str); } function is_qq($str){ //检验qq return preg_match("/^[1-9]\d{4,8}$/", $str); } function is_zip($str){ //检验邮编 return preg_match("/^[1-9]\d{5}$/", $str); } function is_idcard($str){ //检验身份证 return preg_match("/^\d{15}(\d{2}[A-Za-z0-9])?$/", $str); } function is_chinese($str){ 检验是否是中文 return ereg("^[".chr(0xa1)."-".chr(0xff)."]+$",$str); } function is_english($str){ //检验是否是英文 return preg_match("/^[A-Za-z]+$/", $str); } function is_mobile($str){ //检验是否是手机 return preg_match("/^((\(\d{3}\))|(\d{3}\-))?13\d{9}$/", $str); } function is_phone($str){ //建云那是否是电话 return preg_match("/^((\(\d{3}\))|(\d{3}\-))?(\(0\d{2,3}\)|0\d{2,3}-)?[1-9]\d{6,7}$/", $str); } function is_safe($str){ return (preg_match("/^(([A-Z]*|[a-z]*|\d*|[-_\~!@#\$%\^&\*\.\(\)\[\]\{\}<>\?\\\/\'\"]*)|. {0,5})$|\s/", $str) != 0); } }
PS:下面再给大家分享一段代码
<?php /** * @description: 正则表达式匹配 */ class Regex { /** * @手机号 */ public static function Phone($subject) { $pattern='/^(0|86|17951)?(13[0-9]|15[012356789]|1[78][0-9]|14[57])[0-9]{8}$/'; return Regex::PublicMethod($pattern, $subject); } /** * @数字 */ public static function Number($subject) { $pattern='/^[0-9]+$/'; return Regex::PublicMethod($pattern, $subject); } /** * @年份 格式:yyyy */ public static function Year($subject) { $pattern='/^(\d{4})$/'; return Regex::PublicMethod($pattern, $subject); } /** * @月份 格式:mm */ public static function Month($subject) { $pattern='/^0?([1-9])$|^(1[0-2])$/'; return Regex::PublicMethod($pattern, $subject); } /** * @日期 格式:yyyy-mm-dd */ public static function Day($subject) { $pattern='/^(\d{4})-(0?\d{1}|1[0-2])-(0?\d{1}|[12]\d{1}|3[01])$/'; return Regex::PublicMethod($pattern, $subject); } /** * @日期时间 格式:yyyy-mm-dd hh:ii:ss */ public static function DateTime($subject) { $pattern='/^(\d{4})-(0?\d{1}|1[0-2])-(0?\d{1}|[12]\d{1}|3[01])\s(0\d{1}|1\d{1}|2[0-3]):[0-5]\d{1}:([0-5]\d{1})$/'; return Regex::PublicMethod($pattern, $subject); } /** * @邮箱 */ public static function Email($subject) { $pattern='/\w+([-+.]\w+)*@\w+([-.]\w+)*\.\w+([-.]\w+)*/'; return Regex::PublicMethod($pattern, $subject); } /** * @邮编 */ public static function Postcode($subject) { $pattern='/[1-9]\d{5}(?!\d)/'; return Regex::PublicMethod($pattern, $subject); } /** * @有效图片地址 */ public static function Photo($subject) { $pattern='/\b(([\w-]+:\/\/?|www[.])[^\s()<>]+(?:\([\w\d]+\)|([^[:punct:]\s]|\/)))/'; return Regex::PublicMethod($pattern, $subject); } /** * @URL地址 */ public static function UrlAddress($subject) { $pattern='/\b(([\w-]+:\/\/?|www[.])[^\s()<>]+(?:\([\w\d]+\)|([^[:punct:]\s]|\/)))/'; return Regex::PublicMethod($pattern, $subject); } /** * @有效HTTP地址 */ public static function EffectiveHttp($subject) { $pattern='/\b(([\w-]+:\/\/?|www[.])[^\s()<>]+(?:\([\w\d]+\)|([^[:punct:]\s]|\/)))/'; return Regex::PublicMethod($pattern, $subject); } /** * @身份证 */ public static function Identity($subject) { $pattern='/(^\d{15}$)|(^\d{17}([0-9]|X)$)/'; return Regex::PublicMethod($pattern, $subject); } /** * @IPv4 */ public static function Ipv4($subject) { $pattern='/^(((\d{1,2})|(1\d{2})|(2[0-4]\d)|(25[0-5]))\.){3}((\d{1,2})|(1\d{2})|(2[0-4]\d)|(25[0-5]))$/'; return Regex::PublicMethod($pattern, $subject); } /** * @IPv6 */ public static function Ipv6($subject) { $pattern='/^([\da-fA-F]{1,4}:){7}[\da-fA-F]{1,4}$/'; return Regex::PublicMethod($pattern, $subject); } /** * @匹配正则公共方法 */ public static function PublicMethod($pattern, $subject){ if(preg_match($pattern, $subject)){ return true; } return false; } }
