Regular Expressions used by php forms and php forms

Regular Expressions used by php forms and php forms

Php forms are commonly used regular expressions. The Code is as follows:

Function is_email ($ str) {// check email return preg_match ("/^ \ w + ([-+.] \ w +) * @ \ w + ([-.] \ w + )*\. \ w + ([-.] \ w +) * $/", $ str);} function is_url ($ str) {// check the URL return preg_match ("/^ http: \ // [A-Za-z0-9] + \. [A-Za-z0-9] + [\/= \? % \-&_~ '@ [\] \': +!] * ([^ <> \ "]) * $/", $ Str);} function is_qq ($ str) {// verify qq return preg_match ("/^ [1-9] \ d {} $/", $ str);} function is_zip ($ str) {// verify the zip code return preg_match ("/^ [1-9] \ d {5} $/", $ str);} function is_idcard ($ str) {// verify ID card return preg_match ("/^ \ d {15} (\ d {2} [A-Za-z0-9])? $/", $ Str);} function is_chinese ($ str) {check whether it is a Chinese return ereg (" ^ [". chr (0xa1 ). "-". chr (0xff ). "] + $", $ str);} function is_english ($ str) {// check whether return preg_match ("/^ [A-Za-z] + $/", $ str);} function is_mobile ($ str) {// check whether the mobile phone return preg_match ("/^ (\ d {3} \) | (\ d {3 }\-))? 13 \ d {9 }$/", $ str);} function is_phone ($ str) {// do you want to call return preg_match ("/^ (\ d {3} \) | (\ d {3} \-) when creating cloud }\-))? (\ (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: I will share with you a piece of code below.
