Coding Style Comprehensibility introduced by
$return was never initialized. Although not strictly required by PHP, it is generally a good practice to add $return = array(); before regardless.

Adding an explicit array definition is generally preferable to implicit array definition as it guarantees a stable state of the code.

Let’s take a look at an example:

foreach ($collection as $item) {
    $myArray['foo'] = $item->getFoo();

    if ($item->hasBar()) {
        $myArray['bar'] = $item->getBar();
    }

    // do something with $myArray
}

As you can see in this example, the array $myArray is initialized the first time when the foreach loop is entered. You can also see that the value of the bar key is only written conditionally; thus, its value might result from a previous iteration.

This might or might not be intended. To make your intention clear, your code more readible and to avoid accidental bugs, we recommend to add an explicit initialization $myArray = array() either outside or inside the foreach loop.

	/**
5756
	 * This methods removes all of the registered css files on the front end
5757
	 * from Jetpack in favor of using a single file. In effect "imploding"
5758
	 * all the files into one file.
5759
	 *
5760
	 * Pros:
5761
	 * - Uses only ONE css asset connection instead of 15
5762
	 * - Saves a minimum of 56k
5763
	 * - Reduces server load
5764
	 * - Reduces time to first painted byte
5765
	 *
5766
	 * Cons:
5767
	 * - Loads css for ALL modules. However all selectors are prefixed so it
5768
	 *		should not cause any issues with themes.
5769
	 * - Plugins/themes dequeuing styles no longer do anything. See
5770
	 *		jetpack_implode_frontend_css filter for a workaround
5771
	 *
5772
	 * For some situations developers may wish to disable css imploding and
5773
	 * instead operate in legacy mode where each file loads seperately and
5774
	 * can be edited individually or dequeued. This can be accomplished with
5775
	 * the following line:
5776
	 *
5777
	 * add_filter( 'jetpack_implode_frontend_css', '__return_false' );
5778
