How Can I pass a PHP array to a Javascript array

Question

I have an array which have some values stored in it but I want to transfer the elements of that array into javascript array for further processing. How can I do so?

Take a look at "json_encode" – Richard Apr 27 '19 at 11:58 — Richard, Apr 27 '19 at 11:58

You can encode your variable to json using json_encode($php_array). Then on JavaScript side, parse it back using JSON.parse()

<script>
    var foo = <?php echo json_encode($array); ?>;
</script>

No reason to parse it in JavaScript. JSON is already valid JavaScript. This just opens the door for injections. `let foo = = json_encode($array) ?>;` – Peter Apr 27 '19 at 12:06
