It seems like you do not handle an error condition here. This can introduce security issues, and is generally not recommended.
If you suppress an error, we recommend checking for the error condition explicitly:
// For example instead of@mkdir($dir);// Better useif(@mkdir($dir)===false){thrownew\RuntimeException('The directory '.$dir.' could not be created.');}
It seems like you code against a specific sub-type and not the parent class smtech\ReflexiveCanvasLTI\Toolbox as the method smarty_prependTemplateDir() does only exist in the following sub-classes of smtech\ReflexiveCanvasLTI\Toolbox: smtech\CanvasICSSync\Toolbox, smtech\StMarksReflexiveCanvasLTI\Toolbox. Maybe you want to instanceof check for one of these explicitly?
Let’s take a look at an example:
abstractclassUser{/** @return string */abstractpublicfunctiongetPassword();}classMyUserextendsUser{publicfunctiongetPassword(){// return something}publicfunctiongetDisplayName(){// return some name.}}classAuthSystem{publicfunctionauthenticate(User$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 sub-classes
of User which does not have a getDisplayName() method, the code will break.
classAuthSystem{publicfunctionauthenticate(User$user){if($userinstanceofMyUser){$this->logger->info(/** ... */);}// or alternativelyif(!$userinstanceofMyUser){thrownew\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.
