$dir = opendir ($path);
while (false !== ($file = readdir($dir))) {
if (strpos($file, '.png',1)) {
echo "$file <br />";
}
}super short code that lists the .png filenames
obviously the $path variable is the path to the directory.
how can i list them instead in abc order cause of got an order that is not abc!
//put your file in array
$narray[$i]=$file;
//sort it
rsort($narray);
//list it
for($i=0; $i<sizeof($narray); $i++)
echo $narray[$i];

<?php ob_flush(); ?>thanks this seems like the easiest way but where exactly do i put this code? how do incormporate it into my code i posted originally? any help would be appreiciateed.

$dir = opendir ($path);
rsort($dir);
while (false !== ($file = readdir($dir))) {
if (strpos($file, '.png',1)) {
echo "$file <br />";
}
}I dont really have time to test but if this doesnt work then instead of echo, add $file to another array and then sort and printr it.
You could also use a PHP 5 DirectoryIterator from the SPL library.
$iterator = new DirectoryIterator('/path/to/directory/');
foreach($iterator as $fileinfo){
if( !$fileinfo->isDot() && $fileinfo->isFile() ){
echo $fileinfo->getPathname();
}
}DirectoryIterators implement the SplFileInfo class (http://www.php.net/manual/en/class.splfileinfo.php) so anything available there is also immediately available in $fileinfo
From my quick tests and observations this always iterates over a directory alphabetically a -> z but documentation says it does not do any sorting prior.
If you wanted to make it sortable I can show you what a sortable iterator would look like since a DirectoryIterator is a little more "special" then your other iterators.
