Best Practice introduced by
The function say() has been defined more than once; this definition is ignored, only the first definition in _scripts/generate_foolslide.php (L186-186) is considered.

This check looks for functions that have already been defined in other files.

Some Codebases, like WordPress, make a practice of defining functions multiple times. This may lead to problems with the detection of function parameters and types. If you really need to do this, you can mark the duplicate definition with the @ignore annotation.

/**
 * @ignore
 */
function getUser() {

}

function getUser($id, $realm) {

}

See also the PhpDoc documentation for @ignore.
