php身份证校验码的计算例子

public function id_verify($my_id) {

$coefficient = array(7,9,10,5,8,4,2,1,6,3,7,9,10,5,8,4,2);

$remainder_map = array(1,0,'X',9,8,7,6,5,4,3,2);

$count = 0;

for ($i=0; $i < 17; $i++) {

$count += $my_id[$i] * $coefficient[$i];
}

$remainder = $count % 11;

if ($my_id[17] == $remainder_map[$remainder]){

echo 'true';
}else{

echo 'false';
}
}

$body = '44010221990101001';
id_verify($my_id) //就会有结果输出的哦
