You can store all PHP output to a variable and when you have made all the PHP
calculations and outputs, you just echo the stuff out in the right order.
<?PHP
/* do all calculations */
?>
<html>
<!-- make our HTML stuff here, including the output of data generated by PHP -->
<head>
<script type = "text/javascript">
function PageIsLoaded() {
var MyJSVariable = <? echo $MyPHPVariable; ?>;
alert(MyJSVariable);
}
</script>
</head>
<body>
<? echo $phpoutput; ?>
</body>
</html>
That wasn't that difficult, was it?
