Pass a PhP string to Mootools in Wordpress - php

Question

I have a foreach loop that creates a string in php , I'm unable to pass the string value to mootools in wordpress (I'm integrating a MooTool function ) :::
I need to substitute the "hard coded" image URL's in the new Array() (below) with a variable created from my php string eg. new Array( $myimageurl ) :::
I've created a var from the php string even tried json_encode , with no luck :::
window.addEvent("domready", function(){
var counter = 0;
var images = new Array('http://localhost/square/wp-content/uploads/2011/10/test-foo/foo.jpg','http://localhost/square/wp-content/uploads/2011/10/test-foo/foo1.jpg');

Answer 1

er, why not just:
var foo= <?=json_encode(Array("foo.jpg", "bar.jpg"))?>;
EDIT
Since you implied in a comment your files source is comma separated, then do this instead:
<? $files = "foo.jpg,bar.jpg"; ?>
var foo = <?=json_encode(explode(',', $files))?>;
where the array could be anything of any length, read from wherever. it will result in an array literal looking like so:
var foo = ["foo.jpg","bar.jpg"];
// eg use.
foo.each(function(img) {
new Element("img", {src: img}).inject(document.body);
));
nb: just noticed #Marc B has already mentioned json_encode. sorry, will delete

Answer 2

try:
var images = new Array('<?php echo $miImageUrl[0];?>', '<?php echo $miImageUrl[1];?>');
Other way:
<?php
//sample data
$descargables[0] = 'cero';
$descargables[1] = 'uno';
$descargables[2] = 'dos';
$descargables[3] = 'tres';
// end sample data
$arrayToJs="var descargables = new Array();";
for ($i=0; $i < count($descargables); $i++) {
$arrayToJs .= "descargables[" . $i . "]='" . $descargables[$i]. "';";
}
?>
<script>
<?php echo $arrayToJs;?>
idx = 3;
alert("descargable:" + descargables[idx]);
</script>
