php从身份证获取性别和出生年月

//通过身份证号查询出性别与生日
 $birth = strlen($idcard)==15 ? ('19' . substr($idcard, 6, 6)) : substr($idcard, 6, 8);
 $sex = substr($idcard, (strlen($idcard)==15 ? -2 : -1), 1) % 2 ? '1' : '0'; //1为男 2为女

//通过身份证号查询出性别与生日
 if($data['cardtype'] == 'idcard'){
 $data['birth'] = strlen($data['cardno'])==15 ? ('19' . substr($data['cardno'], 6, 6)) : substr($data['cardno'], 6, 8);
 $data['sex'] = substr($data['cardno'], (strlen($data['cardno'])==15 ? -2 : -1), 1) % 2 ? '1' : '0';
