Question

In the function below, I’m seeing to sort the array by alpha. However, it returns bool(true) rather than the actual sorted array. What am I missing?

function get_dirs($dir) {
    $array = array();
    $d = dir($dir);
    while (false !== ($entry = $d->read())){
        if($entry!='.' && $entry!='..') {
            $entry2 = $dir."/".$entry;
            if(is_dir($entry2)) {
                $array[] = $entry;
            }
        }
    }
    $d->close();
    //return $array; THIS WORKS FINE BUT UNSORTED
    return natcasesort($array); //THIS RETURNS A BOOLEAN?
    }

Answer 1

natcasesort returns TRUE on success or FALSE on failure.

Change

return natcasesort($array);

to

natcasesort($array);
return $array;
