Answer 1

<?php 
$n = array('test','test2', 'test3'); 
?>
<script type="text/javascript"> 
    var arr = <?php echo json_encode($n); ?>; // create the JavaScript array
    initArray(arr); // use it
    function initArray(array){
        for(var i = 0; i < array.length; i++){
            alert(array[i]);
        }
    }
</script>

You need to use json_encode to convert a PHP array to a JavaScript one, and output its result while assigning it to a JavaScript variable.

You have to serialize it. Try it with JSON. http://php.net/manual/en/book.json.php
