PHP is server side language. You cannot load like that.

So use ajax instead.

<script>
    if( /Android|webOS|iPhone|iPad|iPod|BlackBerry/i.test(navigator.userAgent) ) {
        var include = "abc.php";
    } else {
        var include = "xyz.php";
    }
    $.ajax({
         url:"url to a function where you can include specified file",
         type:"POST",
         data:{file: include},
         success: function(){
              // you can get executed content of a file here. 
         }
    });

</script>
