Question

I want to split an array in 2 pieces and add the first slice to the end. The point where it should splitten is set in another variable.

$where = 7;
$array = array( 1 => "aaa", 2 => "bbb", 7 => "ccc", 13 => "ddd", 20 => "eee" );

//...code...
//I'd like to have

$array = array(7 => "ccc", 13 => "ddd", 20 => "eee", 1 => "aaa", 2 => "bbb" );

How to achieve that?

Answer 1

foreach($array as $key=>$value)
{
    if ($key === $where)
    {
        break;
    }

    unset($array[$key]);
    $array[$key] = $value;
}
