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 The reason is most likely that a function or method is imcomplete or has been reduced for debug purposes. ![]() |

Unused Code
Comprehensibility

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. ![]() |

You can fix this by adding a namespace to your class:
When choosing a vendor namespace, try to pick something that is not too generic to avoid conflicts with other libraries.
