PHP professional ID card verification, no regular verification of ID card_PHP tutorial

In the past, when I wanted to verify the ID card, we would mostly use regular expressions to determine whether the user input was a 15-digit or 18-digit full number, and then determine whether the ID card was legal. This method is only the most basic. The identity provided below Certificate verification can identify the real thing.

代码如下

复制代码

$IDCard = new IDCard(); var_dump($IDCard::isCard($_GET['card']));   /**  * 身份证处理类  */ class IDCard {       //检证身份证是否正确     public static function isCard($card) {         $card = self::to18Card($card);         if (strlen($card) != 18) {             return false;         }           $cardBase = substr($card, 0, 17);           return (self::getVerifyNum($cardBase) == strtoupper(substr($card, 17, 1)));     }         //格式化15位身份证号码为18位     public static function to18Card($card) {         $card = trim($card);           if (strlen($card) == 18) {             return $card;         }           if (strlen($card) != 15) {             return false;         }           // 如果身份证顺序码是996 997 998 999，这些是为百岁以上老人的特殊编码         if (array_search(substr($card, 12, 3), array('996', '997', '998', '999')) !== false) {             $card = substr($card, 0, 6) . '18' . substr($card, 6, 9);         } else {             $card = substr($card, 0, 6) . '19' . substr($card, 6, 9);         }         $card = $card . self::getVerifyNum($card);         return $card;     }       // 计算身份证校验码，根据国家标准gb 11643-1999     private static function getVerifyNum($cardBase) {         if (strlen($cardBase) != 17) {             return false;         }         // 加权因子         $factor = array(7, 9, 10, 5, 8, 4, 2, 1, 6, 3, 7, 9, 10, 5, 8, 4, 2);           // 校验码对应值         $verify_number_list = array('1', '0', 'X', '9', '8', '7', '6', '5', '4', '3', '2');           $checksum = 0;         for ($i = 0; $i             $checksum += substr($cardBase, $i, 1) * $factor[$i];         }           $mod = $checksum % 11;         $verify_number = $verify_number_list[$mod];           return $verify_number;     } }   ?>
