need to loop through a PHP array in JavaScript

Question

For example I have a PHP array, such as this one

<?php $s= array('a','b','c','d','e','f') ; ?>

And I need to loop through it in JavaScript, any ideas how do I do that?

for ( i=0 ; i < <?php echo sizeof($s) ?> ; i++) {
document.write('<?php echo $s [somehow need to get the 'i' value into here] ?>');
}

Any suggestions? Thanks!

Before your ehco/print or else your php array we make sure it's in JavaScript syntax.

<?php
$s=array('a','b','c','d','e','f');
$s_to_json=json_encode((array)$s);
?>

<script type="text/javascript">

var fromPHP=<? echo $s_to_json ?>;

for (i=0; i<fromPHP.length; i++) {

yourValue=fromPHP[i];

}

</script>
