and let’s assume the following content of Bar.php:
// Bar.phpnamespaceOtherDir;useSomeDir\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.phpnamespaceOtherDir;useSomeDir\FooasSomeDirFoo;// There is no conflict anymore.
