i know this probally a simple question, but it has been stumping me for
quite some time now. How do i pass a php array to a javascript?
i tryed:
<script language="javascript">
var myarray = new Array(<?PHP echo $myarray; ?>);
</script>
but it didn't work. Anybody got any ideas?

You need to generate the javascript array from your PHP array.
Example:
In your script create a php array of the values you wish to use. Using
indeces is not essential. If you do not use them, you can just use a
counter var when you loop through the array to create the indeces for
the JS array.
<?php
$arrayVar = array('first index'=>'item 1', 'second
index'=>'item 2',
'third index'=>'item 3');
$jsVar = "var myArray = new Array();\n";
foreach ($arrayVar as $idx=>$val) {
$jsVar .= "myArray['{$idx}'] = {$val}\n";
}
?>
The final output of this will be:
var myArray = new Array();
myArray['first index'] = 'item 1';
myArray['second index'] = 'item 2';
myArray['third index'] = 'item 3';
HTH,
