Using ajax to call php and return multiple variables?

Question

I am trying to use javascript to call a php script which then will return multiple variables back to my javascript so I can manipulate them.

This is my JS.

Answer 1

You can go for Json in PHP and javascript if you want array in response for a ajax request

PHP Code

$fileId,"num1"=>1,"num2"=>2));
?>

Js Code

jQuery.ajax({
    type: "GET",
    url: 'test.php',
    dataType: "json",
    success: function(response) {
        console.log(response);
        alert(response.num1);
    }
});
