List files in directory

List all files in a directory and return an array.

function dirList ($directory) {
    // create an array to hold directory list
    $results = array();

    // create a handler for the directory
    $handler = opendir($directory);

    // keep going until all files in directory have been read
    while ($file = readdir($handler)) {

        // if $file isn't this directory or its parent,
        // add it to the results array
        if ($file != '.' && $file != '..')
            $results[] = $file;
    }

    // tidy up: close the handler
    closedir($handler);

    // done!
    return $results;
}
