Hussainiat,

It's so simple you will kick yourself. Remember that javascript is delivered as text, just like HTML, so you can write it with php echo or print statemets as if you were typing it yourself at the keyboard.

<?php

$phpmycat = 99;

<script>
alert('<?php echo $phpmyname; ?>');
var myCat = <?php echo $phpmycat; ?>;
onload = function(){
	var myCatContainer = document.getElementById('myCatContainer');
	myCatContainer.innerHTML = myCat;
};
