php不用正则验证真*_PHP教程

直接看代码吧，很简单的一个复制代码 代码如下: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; } } ?>http://www.bkjia.com/www.bkjia.comtruehttp://www.bkjia.com/TechArticle直接看代码吧，很简单的一个
