Getting the names of all files in a directory with PHP

Question

For some reason, I keep getting a '1' for the file names with this code:

if (is_dir($log_directory))
{
    if ($handle = opendir($log_directory))
    {
        while($file = readdir($handle) !== FALSE)
        {
            $results_array[] = $file;
        }
        closedir($handle);
    }
}

When I echo each element in $results_array, I get a bunch of '1's, not the name of the file. How do I get the name of the files?

Don't bother with open/readdir and use glob instead:

foreach(glob($log_directory.'/*.*') as $file) {
    ...
}
