php 身份证验证工具类

//身份证验证private function checkIdCard($idcard){// 只能是18位if (strlen($idcard) != 18) {return false;}// 取出本体码$idcard_base = substr($idcard, 0, 17);// 取出校验码$verify_code = substr($idcard, 17, 1);// 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_code_list = array('1', '0', 'X', '9', '8', '7', '6', '5', '4', '3', '2');// 根据前17位计算校验码$total = 0;for ($i = 0; $i < 17; $i++) {$total += substr($idcard_base, $i, 1) * $factor[$i];}// 取模$mod = $total % 11;// 比较校验码if ($verify_code == $verify_code_list[$mod]) {return true;} else {return false;}}

提取身份证获取生日，性别

$card_number = 110101199003073976;//提取身份证
$cardNumber = strlen($card_number) == 15 ? ('19' . substr($card_number 6, 6)) : substr($card_number, 6, 8);//获取生日
$birthday = substr($cardNumber , 0, 4) . '-' . substr($cardNumber , 4, 2) . '-' . substr($cardNumber , 6, 2);//提取身份证获取性别
$gender = (substr($card_number, (strlen($card_number) == 15 ? -1 : -2), 1) % 2) == 0 ? 2 : 1;
