Php regular expression to determine whether it is a valid ID card number, php to determine the ID card number

This example describes how to use php regular expressions to determine whether a regular ID card number is valid. We will share this with you for your reference. The details are as follows:

/*** Determine whether the ID card number is valid * @ param $ mobile * @ return int */function isCreditNo ($ vStr) {$ vCity = array ('11 ', '12', '13', '14', '15', '21', '22', '23', '31', '32', '33 ', '34 ', '35', '36', '37 ', '41', '42 ', '43', '44 ', '45', '46 ', '50', '51', '52 ', '53', '54 ', '61', '62 ', '63', '64', '65 ', '71 ', '81', '82 ', '91'); if (! Preg_match ('/^ ([\ d] {17} [xX \ d] | [\ d] {15}) $/', $ vStr) return false; if (! In_array (substr ($ vStr, 0, 2), $ vCity) return false; $ vStr = preg_replace ('/[xX] $/I', 'A ', $ vStr); $ vLength = strlen ($ vStr); if ($ vLength = 18) {$ vBirthday = substr ($ vStr, 6, 4 ). '-'. substr ($ vStr, 10, 2 ). '-'. substr ($ vStr, 12, 2);} else {$ vBirthday = '19 '. substr ($ vStr, 6, 2 ). '-'. substr ($ vStr, 8, 2 ). '-'. substr ($ vStr, 10, 2);} if (date ('Y-m-d', strtotime ($ vBirthday ))! = $ VBirthday) return false; if ($ vLength = 18) {$ vSum = 0; for ($ I = 17; $ I >=0; $ I --) {$ vSubStr = substr ($ vStr, 17-$ I, 1); $ vSum + = (pow (2, $ I) % 11) * ($ vSubStr = 'A ')? 10: intval ($ vSubStr, 11);} if ($ vSum % 11! = 1) return false;} return true ;}
