it won't , php will execute in web server and response will sends to browsers. you can use ajax functionality for this scienario — Naisa purushotham

Outside of the function, try this: alert('<?php echo $tags; ?>'); and make sure it's outputting what it should. — awl19

@Naisapurushotham You can use PHP in JQuery if it's inline in the HTML rather than in its own file. Although, I wouldn't suggest people go this route. It's rather clunky and seems unnecessary. — awl19
