			0 ignored issues – show Coding Style Compatibility introduced 2016-05-24 00:01 UTC by Report Bug Copy Issue Report PSR1 recommends that each class must be in a namespace of at least one level to avoid collisions. You can fix this by adding a namespace to your class: namespace YourVendor; class YourClass { } When choosing a vendor namespace, try to pick something that is not too generic to avoid conflicts with other libraries.

			0 ignored issues – show Bug introduced 2016-05-24 00:01 UTC by Report Bug Copy Issue Report It seems like you code against a concrete implementation and not the interface `SS_List` as the method `dataclass()` does only exist in the following implementations of said interface: `ArrayList`, `DataList`, `FieldList`, `HasManyList`, `ManyManyList`, `Member_GroupSet`, `PolymorphicHasManyList`, `RelationList`, `UnsavedRelationList`. Let’s take a look at an example: interface User { /** @return string / public function getPassword(); } class MyUser implements User { public function getPassword() { // return something } public function getDisplayName() { // return some name. } } class AuthSystem { public function authenticate(User $user) { $this->logger->info(sprintf('Authenticating %s.', $user->getDisplayName())); // do something. } } In the above example, the authenticate() method works fine as long as you just pass instances of MyUser. However, if you now also want to pass a different implementation of User which does not have a getDisplayName() method, the code will break. Available Fixes Change the type-hint for the parameter: class AuthSystem { public function authenticate(MyUser $user) { / ... / } } Add an additional type-check: class AuthSystem { public function authenticate(User $user) { if ($user instanceof MyUser) { $this->logger->info(/* ... /); } // or alternatively if ( ! $user instanceof MyUser) { throw new \LogicException( '$user must be an instance of MyUser, ' .'other instances are not supported.' ); } } } Note:* PHP Analyzer uses reverse abstract interpretation to narrow down the types inside the if block in such a case. Add the method to the interface: interface User { /** @return string / public function getPassword(); /* @return string */ public function getDisplayName(); } Loading history...

			0 ignored issues – show Documentation introduced 2016-05-24 00:01 UTC by Report Bug Copy Issue Report The property `LinkedElementID` does not exist on `object<ElementVirtualLinked>`. Since you implemented `__set`, maybe consider adding a @property annotation. Since your code implements the magic setter `_set`, this function will be called for any write access on an undefined variable. You can add the `@property` annotation to your class or interface to document the existence of this variable. <?php /** * @property int $x * @property int $y * @property string $text */ class MyLabel { private $properties; private $allowedProperties = array('x', 'y', 'text'); public function __get($name) { if (isset($properties[$name]) && in_array($name, $this->allowedProperties)) { return $properties[$name]; } else { return null; } } public function __set($name, $value) { if (in_array($name, $this->allowedProperties)) { $properties[$name] = $value; } else { throw new \LogicException("Property $name is not defined."); } } } Since the property has write access only, you can use the @property-write annotation instead. Of course, you may also just have mistyped another name, in which case you should fix the error. See also the PhpDoc documentation for @property. Loading history...
