			0 ignored issues – show Coding Style Compatibility introduced 2016-07-02 12:09 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 2016-07-02 12:09 UTC by Report Bug Copy Issue Report Are you sure the assignment to `$this->error` is correct as `\PSI_Error::singleton()` (which targets `PSI_Error::singleton()`) seems to always return null. This check looks for function or method calls that always return null and whose return value is assigned to a variable. class A { function getObject() { return null; } } $a = new A(); $object = $a->getObject(); The method `getObject()` can return nothing but null, so it makes no sense to assign that value to a variable. The reason is most likely that a function or method is imcomplete or has been reduced for debug purposes. Loading history...

			0 ignored issues – show Unused Code Comprehensibility introduced 2016-07-02 12:09 UTC by Report Bug Copy Issue Report `64%` of this comment could be valid code. Did you maybe forget this after debugging? Sometimes obsolete code just ends up commented out instead of removed. In this case it is better to remove the code once you have checked you do not need it. The code might also have been commented out for debugging purposes. In this case it is vital that someone uncomments it again or your project may behave in very unexpected ways in production. This check looks for comments that seem to be mostly valid code and reports them. Loading history...
