you confusing server-side variables client-side variables,

you need data server, otherwise server knows variable name, string

<script> var int_val=111; function doajax() { var xmlhttp; xmlhttp=new xmlhttprequest(); xmlhttp.open("get","index.php?v="+int_val,true); xmlhttp.send(); } </script> <a href="javascript:doajax();">click here send data server</a> <?php $int_val='' if (isset($_get['v'])) {$int_val=intval($_get['v']);} //now can access `int_val` after js function ran ?>
