Answer 1

Try this one.

<?php
$status = 'active';
$gpa = 'html data here';

if ($_SERVER['REQUEST_METHOD'] === 'POST') {
    if ($status == 'active') {
        return print_r($status);
    }

} else {
include("gp-e.php");
}
?>

$.ajax({
    type:"POST",
    url:"dt.php",
    success:function(data){
        //alert(data);
        if (data.trim() == 'active') 
        {
            alert("status:" + data);
        }
        else
        {
            alert("Status:Inactive");
        }
    }
});
