Question

The following function works in PHP > 5.3 but errors out in older versions. How can I modify this to make it 5.2 safe?

function _iniloader_get_dirs($dir) {
        $dirs = array_filter(scandir($dir), function ($item) use ($dir) {
            return (is_dir($dir.'/'.$item) && $item != "." && $item != "..");
        });
        // Use array_values to reset the array keys:
        return array_values($dirs);
}

5.2 error:

Parse error: syntax error, unexpected T_FUNCTION … on
line 2

You can easily do it w/o the closure, but you will lose some elegance:

function _iniloader_get_dirs($dir) {
    $dirs = array();
    $entries = scandir($dir);
    foreach($entries as $item) {
        if($item === '.' || $item === '..') continue;
        if(!is_dir($dir.'/'.$item)) continue;
        $dirs[] = $item;
    }
    return $dirs;
}
