Bug introduced by
It seems like $type defined by $this->verifyArguments($input, $output) on line 60 can also be of type boolean; however, Cache\CacheBundle\Comman...arCacheForBuiltInType() does only seem to accept string, maybe add an additional type check?

If a method or function can return multiple different values and unless you are sure that you only can receive a single value in this context, we recommend to add an additional type check:

/**
 * @return array|string
 */
function returnsDifferentValues($x) {
    if ($x) {
        return 'foo';
    }

    return array();
}

$x = returnsDifferentValues($y);
if (is_array($x)) {
    // $x is an array.
}

If this a common case that PHP Analyzer should handle natively, please let us know by opening an issue.

Bug introduced by
The class Cache\Taggable\TaggablePoolInterface does not exist. Did you forget a USE statement, or did you not list all dependencies?

This error could be the result of:

1. Missing dependencies

PHP Analyzer uses your composer.json file (if available) to determine the dependencies of your project and to determine all the available classes and functions. It expects the composer.json to be in the root folder of your repository.

Are you sure this class is defined by one of your dependencies, or did you maybe not list a dependency in either the require or require-dev section?

2. Missing use statement

PHP does not complain about undefined classes in ìnstanceof checks. For example, the following PHP code will work perfectly fine:

if ($x instanceof DoesNotExist) {
    // Do something.
}

If you have not tested against this specific condition, such errors might go unnoticed.
