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.

6710
	 * from Jetpack in favor of using a single file. In effect "imploding"
6711
	 * all the files into one file.
6712
	 *
6713
	 * Pros:
6714
	 * - Uses only ONE css asset connection instead of 15
6715
	 * - Saves a minimum of 56k
6716
	 * - Reduces server load
6717
	 * - Reduces time to first painted byte
6718
	 *
6719
	 * Cons:
6720
	 * - Loads css for ALL modules. However all selectors are prefixed so it
6721
	 *		should not cause any issues with themes.
6722
	 * - Plugins/themes dequeuing styles no longer do anything. See
6723
	 *		jetpack_implode_frontend_css filter for a workaround
6724
	 *
6725
	 * For some situations developers may wish to disable css imploding and
6726
	 * instead operate in legacy mode where each file loads seperately and
6727
	 * can be edited individually or dequeued. This can be accomplished with
6728
