I wanted a clarification on the use of namespaces.
If I have two classes in the same namespace, like this:
<?php
namespace Test\Collection;
class First{}
And:
<?php
namespace Test\Collection;
class Second{}
In this case I can use them in this way?
use Test\Collection;
$first = new First();
$second = new Second();
Thanks.
Not quite.
With your example, you'd need:
<?php
use Test\Collection\First;
use Test\Collection\Second;
$first = new First();
$second = new Second();
Or:
<?php
use Test\Collection;
$first = new Collection\First();
$second = new Collection\Second();
See the documentation for more information. This is known as "namespace importing or aliasing".
you can use multiple classes of a namespace like below
use Test\Collection as Container;
$first = new Container\First();
$second = new Container\Second();
I think second solution from @Will may not work at some cases.
for your better understanding take a look at this explanation. Hope this helps
Anyone interested in doing this from PHP 7 onwards, there is another option:
"From PHP 7.0 onwards, classes, functions and constants being imported from the same namespace can be grouped together in a single use statement"
use some\namespace\{ClassA, ClassB, ClassC as C};
use function some\namespace\{fn_a, fn_b, fn_c};
use const some\namespace\{ConstA, ConstB, ConstC};
