Cycler : An easy way to rotate through several values

An easy way to rotate through several values is to use cycler, which takes any number of arguments and cycles through them.

$cycle = cycler('odd', 'even');
$numbers = [1,2,3,4,5,6];
foreach ($numbers as $number) {
    echo "{$number} is {$cycle->next()}";
}
// prints 1 is odd 2 is even 3 is odd 4 is even 5 is odd 6 is even

Installation

You can install the package via composer:

composer require bvtterfly/cycler

Usage

Let's say we want to display ads every three posts on our blog's home page. Then we can use cycler:

$adsCycle = cycler(false, false, true);
foreach ($posts as $post) {
    // show post
    if ($adsCycle->next()) {
        // show add
    }
}

You can access the current item using the current method (in the above example, $adsCycle->current())

Testing
