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.

The call to the method ConsoleController::writehtaccess() seems un-needed as the method has no side-effects.
PHP Analyzer performs a side-effects analysis of your code. A side-effect is
basically anything that might be visible after the scope of the method is left.
If we look at the getEmail() method, we can see that it has no side-effect.
Whether you call this method or not, no future calls to other methods are affected
by this. As such code as the following is useless:
$user=newUser();$user->getEmail();// This line could safely be removed as it has no effect.
On the hand, if we look at the setEmail(), this method _has_ side-effects.
In the following case, we could not remove the method call:
$user=newUser();$user->setEmail('email@domain');// This line has a side-effect (it changes an// instance variable).
Both the $myVar assignment in line 1 and the $higher assignment in line 2
are dead. The first because $myVar is never used and the second because
$higher is always overwritten for every possible time line.
