using drupal_add_js in php code drupal 7

I want to add javascript to a single page. In php block code using the existing module

<?php 
   drupal_add_js('js/leagueSettings.js');
?>

I have a js folder in the modules/php directory where this specific module is.

I have tried using script tags also to no avail.

<script type = "text/javascript" src = "js/leagueSettings.js"></script>

leagueSettings.js is simply

(function ($) {
alert('here');
})(jQuery); 

I have tried it with only the alert..doesn't matter. I have tried using the DIR magic constant in place of the path.. nothing.

Anything I am missing?

EDIT---SOLUTION

//becuase the php block is 'php' module...
drupal_add_js(drupal_get_path('module', 'php') .'/js/leagueSettings.js');
