			0 ignored issues – show Bug Best Practice introduced 2021-10-26 04:39 UTC by Report Bug Copy Issue Report The expression `return new Lagdo\DbAdmin...able, $field->orgtable)` returns the type `Lagdo\DbAdmin\Driver\Entity\StatementFieldEntity` which is incompatible with the return type mandated by `Lagdo\DbAdmin\Driver\Db\...Interface::fetchField()` of `Lagdo\DbAdmin\Driver\Db\StatementFieldEntity`. In the issue above, the returned value is violating the contract defined by the mentioned interface. Let's take a look at an example: interface HasName { /** @return string / public function getName(); } class Name { public $name; } class User implements HasName { /* @return string\|Name */ public function getName() { return new Name('foo'); // This is a violation of the ``HasName`` interface // which only allows a string value to be returned. } } Loading history...
