使用Jquery将变量从PHP文件传递到php文件

Question

I want to pass a variable from file1.php to file2.php using jquery.

file1.php

<?php
    $user_rank = $rank;
?>

file2.php

<?php
    $user_rank = $_GET['user_rank'];
?>

AJAX

function getRank()
{
$.ajax({
       type: "GET",
       url: "file2.php",
       data: ?????,
       success: function(result){
         $("#TargetRank").html(result);
       }
     });         
};

Can anyone help me with this?

The passing part can happen in the script where the variable is defined, so in file1.php. Then you get the following files:

file1.php:

<?php
$user_rank = 123;
?>
<script>
function getRank()
{
$.ajax({
       type: "GET",
       url: "file2.php?user_rank=<?php echo $user_rank; ?>",
       success: function(result){
         $("#TargetRank").html(result);
       }
     });         
};
</script>

file2.php:

<?php
$user_rank = $_GET['user_rank'];
echo $user_rank;
?>
