在通过jQuery加载的PHP中使用全局变量

Question

I am using a jquery function to call a getdata.php file like this -

       $("#tasks").load("getdata.php?choice=" + $("#projects").val()); 

The getdata.php echoes back results dynamically to the callee.

<?php   //getdata.php                       
    global $user_id; //<--These variables are defined in the callee file
    global $con;
    $choice=$_GET['choice'];
    $query="SELECT task_id,title from tasks where user_id=$user_id AND proj_id=$choice";
    $result=mysqli_query($con,$query) or die(mysqli_error($con));
    if((mysqli_num_rows($res))!=0)
    {
        while (list($task_id, $title) = mysqli_fetch_row($result))
          {
           echo "<option value=$task_id>$title</option>";   
      }
     }
     else
     {
        echo "<option>No current Tasks</option>";
     } ?>

Is there any way by which I can access the variables in the callee file from here. I tried using global as would normally be the case with included files but that's not working here.

You may consider using $_SESSION variables to set variables that are available to both your callee file and getdata.php.
