    I'm sorry but I am completely confused about PHP arrays. I read the array section and those two links you posted and I still can't get my code to work. Could you please give me an example of how to transfer a PHP array into a Javascript array. Thanks. :)

    This code is bad...... by for example purposes only;

    <html><head>
<script type="text/javascript">
function parseJS(){
var json=document.getElementById("json_textbox").value;
var obj=eval('('+json+')');

for(val in obj){
  alert(obj[val]); }
}
</script></head>
<body>

<?php
$jsa = array(1,2,3,4,5);
$json=json_encode($jsa);
?>
<form>
<input type="hidden" id="json_textbox" value='<?php print $json; ?>' />
<input type='button' value="Do it!" onclick="parseJS();" />
</form>
<?print $json; ?>
</body></html>
    Code (markup):
    Note: This only uses a 2d array, you will need to process it differently as passing an array of hashes will create a JS object (which, technically everything is in js anyway)....

    --> You could also process the JS inline within php tags in the JS function depending on the requirement of your JS.....

    --> As mentioned previously, You also have interchangeability by using serialize, which is the better option depending on the scope of your project and if the data is likely to be used/needs to be used elsewhere.....
