Generating a javascript array in php with "Foreach" Loop

Question

So I'm generating a javascript array of objects in php with a for loop. My code looks somewhat like this:

<script type="text/javascript">

var items = [ 
<?php foreach($items as $item): ?>
     {
        "title" : "<?php echo $item->title ?>",
        "image" : "<?php echo $item->getImage()?>",
      }, 
 <?php  endforeach ?>
];

</script>

This code will not work, since I end up with an extra comma at the end of my javascript array. Is there an elegant way to deal with that comma that separates the javascript objects?

You should use json_encode().

<?php
    $jsItems = array();
    foreach($items as $item) {
        $jsItems[] = array(
            'title' => $item->title,
            'image' => $item->getImage()
        );
    }
    echo 'var items = '.json_encode($jsItems).';';
?>
