This check compares the return type specified in the @return annotation of a function
or method doc comment with the types returned by the function and raises an issue if they
mismatch.

The call to Director::absoluteBaseURL() has too many arguments starting with '/'.
This check compares calls to functions or methods with their respective definitions.
If the call has more arguments than are defined, it raises an issue.
If a function is defined several times with a different number of parameters, the
check may pick up the wrong definition and report false positives. One codebase
where this has been known to happen is Wordpress.
In this case you can add the @ignorePhpDoc
annotation to the duplicate definition and it will be ignored.
The return type could not be reliably inferred; please add a @return annotation.
Our type inference engine in quite powerful, but sometimes the code does not
provide enough clues to go by. In these cases we request you to add a @return
annotation as described here.
The variable $file does not seem to be defined for all execution paths leading up to this point.
If you define a variable conditionally, it can happen that it is not defined
for all execution paths.
Let’s take a look at an example:
functionmyFunction($a){switch($a){case'foo':$x=1;break;case'bar':$x=2;break;}// $x is potentially undefined here.echo$x;}
In the above example, the variable $x is defined if you pass “foo” or “bar”
as argument for $a. However, since the switch statement has no default
case statement, if you pass any other value, the variable $x would be undefined.
Available Fixes
Check for existence of the variable explicitly:
functionmyFunction($a){switch($a){case'foo':$x=1;break;case'bar':$x=2;break;}if(isset($x)){// Make sure it's always set.echo$x;}}
Define a default value for the variable:
functionmyFunction($a){$x='';// Set a default which gets overridden for certain paths.switch($a){case'foo':$x=1;break;case'bar':$x=2;break;}echo$x;}
Add a value for the missing path:
functionmyFunction($a){switch($a){case'foo':$x=1;break;case'bar':$x=2;break;// We add support for the missing case.default:$x='';break;}echo$x;}
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.
