This check marks access to variables or properties that have not been declared yet. While PHP has no explicit notion of declaring a variable, accessing it before a value is assigned to it is most likely a bug.

6302
	 * from Jetpack in favor of using a single file. In effect "imploding"
6303
	 * all the files into one file.
6304
	 *
6305
	 * Pros:
6306
	 * - Uses only ONE css asset connection instead of 15
6307
	 * - Saves a minimum of 56k
6308
	 * - Reduces server load
6309
	 * - Reduces time to first painted byte
6310
	 *
6311
	 * Cons:
6312
	 * - Loads css for ALL modules. However all selectors are prefixed so it
6313
	 *		should not cause any issues with themes.
6314
	 * - Plugins/themes dequeuing styles no longer do anything. See
6315
	 *		jetpack_implode_frontend_css filter for a workaround
6316
	 *
6317
	 * For some situations developers may wish to disable css imploding and
6318
	 * instead operate in legacy mode where each file loads seperately and
6319
	 * can be edited individually or dequeued. This can be accomplished with
