		0 ignored issues – show Bug introduced 2017-08-02 17:33 UTC by Report Bug Copy Issue Report You have injected the EntityManager via parameter `$entityManager`. This is generally not recommended as it might get closed and become unusable. Instead, it is recommended to inject the ManagerRegistry and retrieve the EntityManager via `getManager()` each time you need it. The `EntityManager` might become unusable for example if a transaction is rolled back and it gets closed. Let’s assume that somewhere in your application, or in a third-party library, there is code such as the following: function someFunction(ManagerRegistry $registry) { $em = $registry->getManager(); $em->getConnection()->beginTransaction(); try { // Do something. $em->getConnection()->commit(); } catch (\Exception $ex) { $em->getConnection()->rollback(); $em->close(); throw $ex; } } If that code throws an exception and the `EntityManager` is closed. Any other code which depends on the same instance of the `EntityManager` during this request will fail. On the other hand, if you instead inject the `ManagerRegistry`, the `getManager()` method guarantees that you will always get a usable manager instance. Loading history...

		0 ignored issues – show Bug Best Practice introduced 2017-08-03 18:03 UTC by Report Bug Copy Issue Report The expression `$isNullable` of type `integer\|null` is loosely compared to `false`; this is ambiguous if the integer can be zero. You might want to explicitly use `=== null` instead. In PHP, under loose comparison (like `==`, or `!=`, or `switch` conditions), values of different types might be equal. For `integer` values, zero is a special case, in particular the following results might be unexpected: 0 == false // true 0 == null // true 123 == false // false 123 == null // false // It is often better to use strict comparison 0 === false // false 0 === null // false Loading history...
