Should the type for parameter $xmlrpc_server not be null|Jetpack_XMLRPC_Server?

This check looks for @param annotations where the type inferred by our type inference engine differs from the declared type.

It makes a suggestion as to what type it considers more descriptive.

Most often this is a case of a parameter that can be null in addition to its declared types.

Bug Best Practice introduced by
The expression $deactivated of type array is implicitly converted to a boolean; are you sure this is intended? If so, consider using ! empty($expr) instead to make it clear that you intend to check for an array without elements.

This check marks implicit conversions of arrays to boolean values in a comparison. While in PHP an empty array is considered to be equal (but not identical) to false, this is not always apparent.

Consider making the comparison explicit by using empty(..) or ! empty(...) instead.

false is of type boolean, but the function expects a string|null.

It seems like the type of the argument is not accepted by the function/method which you are calling.

In some cases, in particular if PHP’s automatic type-juggling kicks in this might be fine. In other cases, however this might be a bug.

We suggest to add an explicit type cast like in the following example:

function acceptsInteger($int) { }

$x = '123'; // string "123"

// Instead of
acceptsInteger($x);

// we recommend to use
acceptsInteger((integer) $x);

It seems like $redirect defined by parameter $redirect on line 4527 can also be of type string; however, Jetpack::build_authorize_url() does only seem to accept boolean, maybe add an additional type check?

This check looks at variables that have been passed in as parameters and are passed out again to other methods.

If the outgoing method call has stricter type requirements than the method itself, an issue is raised.

An additional type check may prevent trouble.

6342
	 *
6343
	 * Pros:
6344
	 * - Uses only ONE css asset connection instead of 15
6345
	 * - Saves a minimum of 56k
6346
	 * - Reduces server load
6347
	 * - Reduces time to first painted byte

6349
	 * Cons:
6350
	 * - Loads css for ALL modules. However all selectors are prefixed so it
6351
	 *		should not cause any issues with themes.
6352
	 * - Plugins/themes dequeuing styles no longer do anything. See

	 *		jetpack_implode_frontend_css filter for a workaround
6354
	 *
6355

6356
	 * instead operate in legacy mode where each file loads seperately and
6357
