Question

How can I input results of a PHP array inside a JS-file?

I have this PHP-snippet which returns an Array:

$activiteiten = Project::getProjectnames($_DB);
if(!empty($activiteiten)) {
    foreach($activiteiten as $k => $v) {
        $projectNames[] = $v['project'];
    }
}

How can I get these values inside this JS:

<script>
    $(function() {
        var availableTags = [
            "Option 1",
            "Option 2",
            "Option 3",
            "Option 4"
        ];
        $( "#tags" ).autocomplete({
            source: availableTags
        });
    });
</script>

I want the PHP array in stead of the Option 1, Option 2, Option 3,… But how do I do this?

I’m generating the JS by using a PHP echo-call.

var availableTags = <?php echo json_encode($projectNames); ?>;
