You have to place this below code at the top part of your test.php page

<script>
var filter = '<?php echo $my_cat>';
</script>

and simply you can check it on your external.js file by alert

alert(filter);

<?php 
   function showme(){
   echo "HelloWorld";
}
?>    

<script type="text/javascript">
     var my_var = '<?php echo showme(); ?>' ;
</script>

You can also use short tags.

<script>

var filter = '<?=$my_cat?>';

</script>
