UnnecessaryUseAlias

info on by default quick-fix

Group: Code style · PhpStorm name: UnnecessaryUseAliasInspection

An import alias identical to the last segment of the imported name (use App\Mail\Sender as Sender;) changes nothing. Drop the as clause.

Example

Before

<?php
namespace Shop;

use Psr\Log\LoggerInterface as LoggerInterface;
use \Redis as Redis;
use function Util\slugify as slugify;
use Psr\Cache\{CacheItemInterface as CacheItemInterface, InvalidArgumentException};
use Psr\Clock\ClockInterface as Clock;
use Psr\Link\LinkInterface as linkinterface;

class Cart {
    use \Shop\Traits\Totals { total as total; }
}

After fix

<?php
namespace Shop;

use Psr\Log\LoggerInterface;
use \Redis;
use function Util\slugify;
use Psr\Cache\{CacheItemInterface, InvalidArgumentException};
use Psr\Clock\ClockInterface as Clock;
use Psr\Link\LinkInterface as linkinterface;

class Cart {
    use \Shop\Traits\Totals { total as total; }
}

Reported:

• line 4: Alias LoggerInterface repeats the imported name; remove it.
• line 5: Alias Redis repeats the imported name; remove it.
• line 6: Alias slugify repeats the imported name; remove it.
• line 7: Alias CacheItemInterface repeats the imported name; remove it.
