<?php

/*
  * Usage:
  * wp_enqueue_script( $handle, $src, $deps, $ver, $in_footer );
  *
  * @param string      $handle    Name of the script.
  * @param string|bool $src       Path to the script from the root directory of WordPress. Example: '/js/myscript.js'.
  * @param array       $deps      An array of registered handles this script depends on. Default empty array.
  * @param string|bool $ver       Optional. String specifying the script version number, if it has one. This parameter
  *                               is used to ensure that the correct version is sent to the client regardless of caching,
  *                               and so should be included if a version number is available and makes sense for the script.
  * @param bool        $in_footer Optional. Whether to enqueue the script before </head> or before </body>.
  *                               Default 'false'. Accepts 'false' or 'true'.
