How to use PHP Variables in Javascript/Jquery

Question

I have 2 PHP Variables: $category1 and $category2

I want the URL to be like this:

?category1=$category1&category2=$category2&q=str

I only know PHP, I have very less knowledge of JS/Jquery, can someone help me in this small thing?

I tried this:

var category1 = '<?php echo $category1; ?>';
var category2 = '<?php echo $category2; ?>';

But, idk what to write here

xmlhttp.open("GET","getuser.php?q="+str,true);
