I was writing out a method today that accepted an array of items as a parameter. I always try to type the array using something like: `MyObject[]`. That got me thinking about what type I should use though? Do you use `array`, `iterable`, or `Collection` if you're in the Laravel world?

Some examples:

    /**
     * @param  MyObject[]  myArray
     */
    public function withArray(array $myArray)
    {
        //
    }

    /**
     * @param  MyObject[]  myArray
     */
    public function withIterable(iterable $myIterable)
    {
        // Using iterable will support both arrays or Laravel collections.
        // However, you may need to use the spread operator to convert 
        // back to array if needed.
        $array = [...$myIterable];
    }

    /**
     * @param  Collection<MyObject>  myArray
     */
    public function withIterable(Collection $myCollection)
    {
        // This gives all the power of collections which is great,
        // however, it requires Laravel collections so not as useful
        // outside a Laravel application.
    }

good question; i typically just use array, and specify the array shape using the generic syntax: array<int, something>.
