<script>
var queryString = window.location.search;
queryString = queryString.substring(1);
</script>
<?php
include("assignmentd.php");
$array;
$id=$_COOKIE['id'];
$count = "<script>document.write(queryString)</script>";
$count1=$count;
echo $count;
print_r(parse_str($count1,$array));
print_r($array);
//$q3="INSERT INTO previous_year(clicks)VALUES('$fcount') where id='$id'";
        //$m3=mysqli_query($conn,$q3);
?>

只能解析 URL 字符串。解析字符串中不能有脚本标签，也不能像 html 一样在 PHP 上执行 javascript。

使用表单提交数据，然后使用 $_GET 访问它。
