			0 ignored issues – show Bug introduced 2017-02-17 22:23 UTC by Report Bug Copy Issue Report This use statement conflicts with another class in this namespace, `erdiko\core\ToroHook`. 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.

			0 ignored issues – show Unused Code Comprehensibility introduced 2017-01-20 00:37 UTC by Report Bug Copy Issue Report `47%` of this comment could be valid code. Did you maybe forget this after debugging? Sometimes obsolete code just ends up commented out instead of removed. In this case it is better to remove the code once you have checked you do not need it. The code might also have been commented out for debugging purposes. In this case it is vital that someone uncomments it again or your project may behave in very unexpected ways in production. This check looks for comments that seem to be mostly valid code and reports them. Loading history...

Although not strictly required by PHP, it is generally a good practice to add `$vars = array();` before regardless. Adding an explicit array definition is generally preferable to implicit array definition as it guarantees a stable state of the code. Let’s take a look at an example: foreach ($collection as $item) { $myArray['foo'] = $item->getFoo(); if ($item->hasBar()) { $myArray['bar'] = $item->getBar(); } // do something with $myArray } As you can see in this example, the array `$myArray` is initialized the first time when the foreach loop is entered. You can also see that the value of the `bar` key is only written conditionally; thus, its value might result from a previous iteration. This might or might not be intended. To make your intention clear, your code more readible and to avoid accidental bugs, we recommend to add an explicit initialization `$myArray = array()` either outside or inside the foreach loop.
