It is generally recommended to explicitly declare the visibility for methods.
Adding explicit visibility (private, protected, or public) is generally
recommend to communicate to other developers how, and from where this method
is intended to be used.
$columns was never initialized. Although not strictly required by PHP, it is generally a good practice to add $columns = array(); before regardless.
Adding an explicit array definition is generally preferable to implicit array
definition as it guarantees a stable state of the code.
Let’s take a look at an example:
foreach($collectionas$item){$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.
