Question

I have this PHP file wherein I need this javascript variable available (inside the same file) to be pass on my PHP variable, something like this.

myfile.php contais:

    var testing  = ["EWMLMc3ES3I", "RSdKmX2BH7o", "SIXwlxhjaKY", "acp8TbBPVos", "6GpKR4-TLoI", "XLKLkTnKRwg", "6WPELkw5kD0"];

and I want to make it like this

 testing = <?php $new_testing ?>

---

I need a suggestion maybe a jquery snippet but with something like my scenario which is a javascript in a php file.

---

edit: additional info, the reason for this is , because there’s another javascript codes (not on the same file but rather had it include via external JS) that needs that particular PHP variable.
so say here’s the logic:

1. javascript_variable —> php_variable (passing the javascript variable to php) then,
2. php_variable –> another_javascript_variable (pass the php to another javascript file)
3. the another_javascript_variable will the be executed by that external javascript file

On your PHP side, use json_encode() to convert your php array to a suitable format to pass it to the javascript.

PHP:

$var = array( 'lorem', 'ipsum', 'dolor');
$json_var = json_encode($var);
$parameter = array( 'js_var' => $json_var );
wp_enqueue_script('my_script');
wp_localize_script('my_script', 'object_name', $parameter); 

Javscript:

<script>
my_var = jQuery.parseJSON(object_name.js_var);
alert(my_var); 
</script>
