			0 ignored issues – show Bug introduced 2021-08-20 05:37 UTC by Report Bug Copy Issue Report This use statement conflicts with another class in this namespace, `Omnipay\GoCardless\Message\AbstractRequest`. Consider defining an alias. Let?s assume that you have a directory layout like this: . \|-- OtherDir \| \|-- Bar.php \| `-- Foo.php `-- SomeDir `-- Foo.php and let?s assume the following content of `Bar.php`: // Bar.php namespace OtherDir; use SomeDir\Foo; // This now conflicts the class OtherDir\Foo If both files `OtherDir/Foo.php` and `SomeDir/Foo.php` are loaded in the same runtime, you will see a PHP error such as the following: PHP Fatal error: Cannot use SomeDir\Foo as Foo because the name is already in use in OtherDir/Foo.php However, as `OtherDir/Foo.php` does not necessarily have to be loaded and the error is only triggered if it is loaded before `OtherDir/Bar.php`, this problem might go unnoticed for a while. In order to prevent this error from surfacing, you must import the namespace with a different alias: // Bar.php namespace OtherDir; use SomeDir\Foo as SomeDirFoo; // There is no conflict anymore.

			0 ignored issues – show Bug Best Practice introduced 2021-08-20 05:37 UTC by Report Bug Copy Issue Report The expression `return $this` returns the type `Omnipay\GoCardless\Message\WebhookNotification` which is incompatible with the return type mandated by `Omnipay\Common\Message\R...stInterface::sendData()` of `Omnipay\Common\Message\ResponseInterface`. 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...
