[5.4] Create a static "times" method on the collection

[JosephSilber]

This is extremely useful to whip up a quick list of stuff, whether in a test or in production:

$slugs = Collection::times(5, function ($number) {
    return 'slug-'.$number;
});

// ['slug-1', 'slug-2', 'slug-3', 'slug-4', 'slug-5'];

You can also use it with factories, for example if you want sequential numbers:

$products = Collection::times(5, function ($number) {
    return factory(Product::class)->create(['name' => 'Product #'.$number]);
});

The name of the method needs work maybe? times in Ruby is more like an each operation, so it's a little confusing to me?

[JosephSilber]

This is an each (plus a map).

There's nothing stopping you from just ignoring everything else:

Collection::times(5, function () {
    echo 'I will be logged 5 times.';
});

Collection::repeat?

[jmarcher]

Failing test:

    public function testTimesWithZeroMethod()
    {
        $this->assertEquals([], Collection::times(0, function ($number) {
            return 'do-not-enter-'.$number;
        })->all());
    }

Do we really have to check for that? And what if you pass it a negative number?

[jmarcher]

Negative numbers do not make sense but if we I see a method called "times" and give a 0 as parameter I expect that it executes zero times

[JosephSilber]

@jmarcher makes sense. Added it 👍
