So how to format string in input box so PHP take it like variables.

Eek, don't. Construct the string in PHP, don't send it from JavaScript to be eval()'d! Doing so would be a giant security hole. — Michael Berkowski, Jan 31 '13 at 01:09
a) you can use javascript rand functions. b) you can split string in server and do eval on some php codes and get their result and process it — Vahid Farahmand, Jan 31 '13 at 01:09

You can create javascript using php. Something like this:

<script type="text/javascript">
<?php 
    $anyVar = "BONJOUR";    
?>
var value = "<?php echo $anyVar; ?>" ;
alert(value);
</script>

In the example I'm passing the value of my var $anyVar in PHP to the value var in javascript. So after the page loads and the script is parsed, you'll end up with something like this:

<script type="text/javascript">
var value = "BONJOUR" ;
alert(value);
</script>

You can as well write js code like this:

<script type="text/javascript">
<?php 
    $anyVar = "BONJOUR";    
?>
var value = "<?php echo $anyVar; ?>" ;
<?php echo 'alert(value);' ?>
</script>

Hope this helps.
