php表单习惯用的正则表达式
这篇文章通过实例代码给大家介绍了php表单习惯使用的正则表达式,非常不错,具有参考借鉴价值,需要的朋友参考下吧。
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);
- }
- }
