You should use the first method, although I recommend against the use
of <?= because it is deprecated in PHP5.3 and will be removed in PHP6.
I usually do it like this:
<script type="text/javascript">
(function(){
this.Config = <?php echo json_encode(array(...)); ?>
})();
</script>
which creates a global variable "Config".
