$arr = [1,2,3,4,5,6,7,8,9,10];
foreach( array_chunk($arr, 3) as $x ) {
    echo json_encode($x) . "\n";
}

$arr = [1,2,3,4,5,6,7,8,9,10];
$chunk_size = 3;
foreach( range(0, count($arr), $chunk_size) as $i ) {
    $chunk = array_slice($arr, $i, $chunk_size);
    echo json_encode($chunk) . "\n";
}

$arr = ['hello', 'world', 123, 'lorem', 456, 'ipsum', 789];
$chunk_size = 3;
foreach( range(0, count($arr), $chunk_size) as $i ) {
    $chunk = array_slice($arr, $i, $chunk_size);
