TYPO3 Core

The change in #96457 causes problems with PHPStan after updating to 11.5.5.

Given this code:

$qb = $this->connection->createQueryBuilder();
$result = $qb
    // ...
    ->where(
        // returns string
        $qb->expr()->eq('CType', $qb->createNamedParameter($someVariable)
    )
    ->execute()
;

we now get an error

Parameter #1 ...$predicates of method TYPO3\CMS\Core\Database\Query\QueryBuilder::where() expects array<int, mixed>|Doctrine\DBAL\Query\Expression\CompositeExpression, string given.

because |CompositeExpression was added. I made a short comparison:

• Before (11.5.4): https://phpstan.org/r/d29e3b2b-d642-4792-9d4b-62d225ad911e (works)
• After (11.5.5): https://phpstan.org/r/2334fbfc-75ae-4956-94af-b583555c61d3 (fails)

A possible solution would be to

1. either move the |CompositeExpression to the existing array: https://phpstan.org/r/3f42d413-f44d-4b4e-b82a-57a231a7f69e or
2. resolve the array: https://phpstan.org/r/915d50c1-6bb8-48be-88f7-21b147049acd
