Sorting Values Retrieved From Directory

[billhobbs]

I have a script that retrieves the names of photos in a photo directory. I want to sort them by the names, but my sorting isn't working. Everything seems to work except the order is wrong. My code is below. Any help is appreciated.

$path = "../arrangements";
if(isset($_POST['file']) && is_array($_POST['file']))
{
    
    foreach($_POST['file'] as $file)
    {    
        unlink($path . "/" . $file) or die("Failed to <strong class='highlight'>delete</strong> file");
    }
}

$path = "../arrangements";
$dir_handle = @opendir($path) or die("Unable to open folder");
while (false !== ($file = readdir($dir_handle))) 
{
sort($file);
if($file == ".")
continue;
if($file == "..")
continue;
echo "<img src='../arrangements/$file' alt='$file'><br />";
    $filename = substr($file, 0, strrpos($file, "."));
echo $filename;
}

Store the filenames in an array then sort the array.

Try using glob() instead.

Of all the PHP 4 and older-style code out there still being spread around the internet, opendir/readdir/closedir must be the most resilient. There is virtually no reason whatsoever to use it anymore, and yet people do.

Did you even TRY to debug this yourself?  If you had RTFM under 'readdir' you would have found your error in 1 minute.
