passing list <Class> $obj to a mthod in PHP / enabling Type hinting

Here is my method signature:

protected function updateFeeComponent(\FeeComponent $FeeList, $shipment_id, $item_id)
foreach($FeeList as $fee)
//other stuff

and I am calling it as:


is of
@var List<FeeComponent> ItemFeeList

How can I pass LIST of Custom object as a parameter to a function?


I am using PHPStorm V-9, and was integrating Laravel-Amazon-mws library
To enable type-hint / Intellicode / Available method list ( whatever you name it), I needed to mention the
type. I fell in to this problem. I know

instead of

So, my question was about type hinting, at the moment of asking this question, I admit, I failed to think of

As far as I am aware, the closest you can get to what you want is something like:

 * @param FeeComponent[] $FeeList
protected function updateFeeComponent(array $FeeList) {
    // ...

Where you annotate with PHPDoc the type for $FeeList as being an array of FeeComponent and use PHP type hinting to specify the required type as being an array.

In an IDE that supports reading PHPDoc like PHPStorm, this will treat each element in the input array correctly as a FeeComponent and provide valid hinting e.g.

foreach ($FeeList as $fee) {
    $fee-> // Be provided with properties and methods of FeeComponent
           // in hints here.
