Passing PHP variables to Javascript

Can anyone tell me the best way to pass a PHP array into a Javascript array? It just crossed my mind just now.

I'm not too familiar wit JSON Or XML but here's what I have so far but it doesn't work though. What's wrong with it?

var js_arr = [];
<?php
$tempo_arr = array('list', 'of', 'elements');
foreach($tempo_arr as $element)
{
	echo "js_arr.push($element);\n";
}
?>
alert(js_arr);

Code (markup):

 

You should probably do something like:

echo "js_arr.push('$element');\n";

PHP:

Or if you have PHP 5.2+, you can just do:

echo 'js_arr = ' . json_encode($temp_arr);

 

Hey, it worked. Thanks!
