How can I suppress PHPCS warnings using comments?

Question

My TestMyClass.php has two class definitions in the same file (unit testing class), and PHP Code Sniffer complains about each class must be in a file by itself<

Answer 1

With the following comments you can ignore whatever part of a file you would like.

Ignore all the sniffs for the file:

Ignore only the current and next line:

// phpcs:ignore
public function store($myArray)

Ignore the current line:

public function store($myArray) // phpcs:ignore

Ignore a certain amount of lines in a file:

// phpcs:disable
public function store($myArray): void
{
    if (count($myArray) > 3) {
        // Humongous amount of legacy code you don't want to look at
    }

    return;
}
// phpcs:enable

With // phpcs:ignore and // phpcs:disable you can also specify which messages, sniffs, categories or standards you would like to disable, for example:

// phpcs:ignore Squiz.Arrays.ArrayDeclaration.SingleLineNotAllowed
$foo = [1,2,3];
