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`: // Bar.php namespace OtherDir; use SomeDir\Foo; // This now conflicts the class OtherDir\Foo If both files `OtherDir/Foo.php` and `SomeDir/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 before `OtherDir/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: // Bar.php namespace OtherDir; use SomeDir\Foo as SomeDirFoo; // There is no conflict anymore.
