Installation

You can install the package via composer:

composer require isaeken/loops

Usage

Basic Usage

loop(5, function (\IsaEken\Loops\Index $index) {
    return $index->odd;
}); // [false, true, false, true, false]

Async Usage

$loop = async_loop(5, function (\IsaEken\Loops\Index $index) {
    return $index->even;
});

// ...

await($loop); // [true, false, true, false, true]

Using with class method

$callback = new class implements \IsaEken\Loops\Contracts\LoopCallback {
    public function __invoke(Index $index, Loop $loop = null): int
    {
        return $index->index;
    }
};

$loop = new Loop(2, $callback);
$loop->run();
$loop->results(); // [0, 1]

Get current loop

loop(2 ,function (\IsaEken\Loops\Index $index, \IsaEken\Loops\Loop $loop) {
    return [
        'iteration' => $index->iteration,
        'index'     => $index->index,
        'remaining' => $index->remaining,
        'count'     => $index->count,
        'first'     => $index->first,
        'last'      => $index->last,
        'odd'       => $index->odd,
        'even'      => $index->even,
    ];
});
// [
//  [
//    'iteration' => 1,
//    'index' => 0,
//    'remaining' => 1,
//    'count' => 2,
//    'first' => true,
//    'last' => false,
//    'odd' => false,
//    'even' => true,
//  ],
//  [
//    'iteration' => 2,
//    'index' => 1,
//    'remaining' => 0,
//    'count' => 2,
//    'first' => false,
//    'last' => true,
//    'odd' => true,
//    'even' => false,
//  ]
// ]

Break the loop

loop(3, function (\IsaEken\Loops\Index $index, \IsaEken\Loops\Loop $loop) {
    if ($index->index > 1) {
        $loop->break();
    }
    
    return $index->index;
}); // [0, 1]

Loop random times

loop_random(function (\IsaEken\Loops\Index $index, \IsaEken\Loops\Loop $loop) {
    return $index->index;
}); // executed random times.

$min = 5;
$max = 10;

loop_random(function (\IsaEken\Loops\Index $index, \IsaEken\Loops\Loop $loop) {
    return $index->index;
}, $min, $max);

Loop random with seed

loop_random(function (\IsaEken\Loops\Index $index) {
    return $index->even;
}, seed: 123456789);
