Parse variable to class object

Question

Following situation:

foreach ($this->allEvents as $event) {
    //use $event here
}

allEvents (array) stores several objects of Event class. Now I want that my IDE (PhpStorm) suggests me all methods that $event has. But unfortunately is does not know that $event is a Event object.

Is there any possibility to convert $event to an object of Event class? Like type conversions in Java: (Event) event

The problem probably lies somewhere in the way you annotated the property allEvents in your class. If you properly annotated allEvents or have a proper getter that has return annotations it should work. Make sure you are not just dynamically declaring the property because PHPStorm can't know whats going on then. — xate

@Xatenev oh my gosh... I got it. I annotated it with (@ var array Event) but the proper version is @ var Event[]. Thank you so much :) — H4rd_B4se

In Eclipse you can do \*@var $var Object*/ just before the foreach. Not sure if PhpStorm has a similar method. — ArtisticPhoenix

Thanks to @Xatenev The problem was a wrong annotation of $allEvents. It has to look like

/**
 * @var Event[]
 */
private $allEvents = array();

so PhpStorm will understand it correctly as an array of Event objects

Alternatively you can use assert inside foreach to make your IDE aware of the type of the variable:

foreach ($this->allEvents as $event) {
    assert($event instanceof Event);
    //use $event here
}

Assertions are not executed in the production code so there is no additional overhead of using them.
