How to “flatten” a multi-dimensional array to simple one in PHP?

Question

It\'s probably beginner question but I\'m going through documentation for longer time already and I can\'t find any solution. I thought I could use implode for each dimensio

Answer 1

you can try this:

function flat_an_array($a)
{
    foreach($a as $i)
    {
        if(is_array($i)) 
        {
            if($na) $na = array_merge($na,flat_an_array($i));
            else $na = flat_an_array($i);
        }
        else $na[] = $i;
    }
    return $na;
}
