This use statement conflicts with another class in this namespace,
Aggrego\FragmentedDataBoard\Board\Metadata . Consider defining an alias.
Let?s assume that you have a directory layout like this: .
|-- OtherDir
| |-- Bar.php
| `-- Foo.php
`-- SomeDir
`-- Foo.php
and let?s assume the following content of // Bar.php
namespace OtherDir;
use SomeDir\Foo; // This now conflicts the class OtherDir\Foo
If both files PHP Fatal error: Cannot use SomeDir\Foo as Foo because the name is already in use in OtherDir/Foo.php
However, as // Bar.php
namespace OtherDir;
use SomeDir\Foo as SomeDirFoo; // There is no conflict anymore.

In this branch, the function will implicitly return
null which is incompatible with the type-hinted return Aggrego\Domain\Board\Board . Consider adding a return statement or allowing null as return value.
For hinted functions/methods where all return statements with the correct type are only reachable via conditions, ?null? gets implicitly returned which may be incompatible with the hinted type. Let?s take a look at an example: interface ReturnsInt {
public function returnsIntHinted(): int;
}
class MyClass implements ReturnsInt {
public function returnsIntHinted(): int
{
if (foo()) {
return 123;
}
// here: null is implicitly returned
}

Let?s assume that you have a directory layout like this:
and let?s assume the following content of
Bar.php
:If both files
OtherDir/Foo.php
andSomeDir/Foo.php
are loaded in the same runtime, you will see a PHP error such as the following:PHP Fatal error: Cannot use SomeDir\Foo as Foo because the name is already in use in OtherDir/Foo.php
However, as
OtherDir/Foo.php
does not necessarily have to be loaded and the error is only triggered if it is loaded beforeOtherDir/Bar.php
, this problem might go unnoticed for a while. In order to prevent this error from surfacing, you must import the namespace with a different alias:
