			0 ignored issues – show Coding Style Comprehensibility introduced 2016-03-31 13:05 UTC by Report Bug Copy Issue Report `$toggleButton` was never initialized. Although not strictly required by PHP, it is generally a good practice to add `$toggleButton = 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.

			0 ignored issues – show Bug introduced 2016-03-31 13:05 UTC by Report Bug Copy Issue Report It seems like `$this->form` can also be of type `object<yii\bootstrap\ActiveForm>`; however, `yii\base\Widget::begin()` does only seem to accept `array`, maybe add an additional type check? If a method or function can return multiple different values and unless you are sure that you only can receive a single value in this context, we recommend to add an additional type check: /** * @return array\|string */ function returnsDifferentValues($x) { if ($x) { return 'foo'; } return array(); } $x = returnsDifferentValues($y); if (is_array($x)) { // $x is an array. } If this a common case that PHP Analyzer should handle natively, please let us know by opening an issue.
