Symfony version(s) affected

5.4.7

Description

\Symfony\Component\Cache\Adapter\PdoAdapter::__construct() 1st param is $connOrDsn.
The DocBlock Comment currently section says:
@param \PDO|string $connOrDsn, however it can also be of type \Doctrine\DBAL\Connection.

Because of the DocBlock Comment is currently missing the Connection type, some static analyzers (phpstan) fails when we provide a Connection object.

How to reproduce

use Doctrine\DBAL\DriverManager;
use Symfony\Component\Cache\Adapter\PdoAdapter;

$connUrl = 'mysql://user:passsword@127.0.0.1/db_name';
$conn = DriverManager::getConnection( [ 'url' => $connUrl ]);
new PdoAdapter( $conn, 'mycache', 3600 );

Then run phpstan on it

Possible Solution

in vendor/symfony/cache/Adapter/PdoAdapter.php Link to GitHub line change line 59 to this:

* @param \PDO|Connection|string $connOrDsn
