How to create an array with objects in php

I want to have an array with objects. For example.

public $aCarObjects = array();

$aCars = array('Audi','BMW','Ford');



foreach($aCars as $car){

  array_push($aCarObjects, new Car($car));

}



// Simplified class

class Car implements C{

   private $carName;



  public function __construct($carName){

     $this->carName = $carName;

  } 

}

interface C {}

This is a very shortened version of what I am trying. The class Car contains some info about the car.

When I am using the Interface C in the Car class. I cannot add objects to the array. Why is that so?

Yes, you can use "new" inside array_push. A shorthand version (just a simpler syntax) is $aCarObjects = new Car($car);

@Jeff array_push isn't the same as $array - it only does the same thing in most cases

Use modern syntax: $arrray replace array_push($array) since at least 4 years! It hurt to see

This error has nothing to do with arrays, it's a class hoisting bug (feature?) which is fixed by moving your class definition above the call to new Car. Apparently, PHP does not hoist class definitions if they implement an interface.

Here's a minimal example of the phenomenon.

Works:

new Foo();

class Foo {}

interface Bar {}

Doesn't:

new Foo(); # <-- error: Class 'Foo' not found

class Foo implements Bar {}

interface Bar {}

Perhaps this is a candidate for PHP Sadness?

Here's a working version of your code that also addresses a stray public keyword in line 1:

interface C {}



class Car implements C {

    private $carName;



    public function __construct($carName) {

        $this->carName = $carName;

    }

}



$aCarObjects = ;

$aCars = ['Audi', 'BMW', 'Ford'];



foreach ($aCars as $car) {

    array_push($aCarObjects, new Car($car));

}



print_r($aCarObjects);

Output:

Array

(

    [0] => Car Object

        (

            [carName:Car:private] => Audi

        )



    [1] => Car Object

        (

            [carName:Car:private] => BMW

        )



    [2] => Car Object

        (

            [carName:Car:private] => Ford

        )



)

Try it!

Thanks for the comment. The construct part was a typo the other things are nice to know. My problem is the interface, which I did not mention.

The issue is that you've declared the class after the call to new Car. Move the class definition to the top of your file; it's not hoisted if it implements an interface, which is pretty strange.
