Coding Style Compatibility introduced by
The method activate_module() contains an exit expression.

An exit expression should only be used in rare cases. For example, if you write a short command line script.

In most cases however, using an exit expression makes the code untestable and often causes incompatibilities with other libraries. Thus, unless you are absolutely sure it is required here, we recommend to refactor your code to avoid its usage.

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.

The method admin_page_load() contains an exit expression.

An exit expression should only be used in rare cases. For example, if you write a short command line script.

In most cases however, using an exit expression makes the code untestable and often causes incompatibilities with other libraries. Thus, unless you are absolutely sure it is required here, we recommend to refactor your code to avoid its usage.

5743

5744
	 * from Jetpack in favor of using a single file. In effect "imploding"
5745
	 * all the files into one file.
5746
	 *
5747
	 * Pros:
5748
	 * - Uses only ONE css asset connection instead of 15
5749
	 * - Saves a minimum of 56k
5750
	 * - Reduces server load
5751
	 * - Reduces time to first painted byte
5752
	 *
5753
	 * Cons:
5754
	 * - Loads css for ALL modules. However all selectors are prefixed so it
5755
	 *		should not cause any issues with themes.
5756
	 * - Plugins/themes dequeuing styles no longer do anything. See
5757
	 *		jetpack_implode_frontend_css filter for a workaround
5758
	 *
5759
	 * For some situations developers may wish to disable css imploding and
5760
	 * instead operate in legacy mode where each file loads seperately and
5761
	 * can be edited individually or dequeued. This can be accomplished with
5762
	 * the following line:
