You strongly need to review how PHP works !

PHP is a SERVER-side language while JavaScript is a CLIENT-side ! PHP is always interprated on the server BEFORE being sent to the client ! You could use AJAX to send the value of "p" to a script which queries the database, and then returns the result...
