Re: Creating & sorting associative or 2-d array

Hey Patrick, Something like this : $dir = '.'; $dir_handle = opendir($dir); // Create array with last modified as value, filename as key. // filename is to be key as it is unique, last modified is not. while ($file_piece = readdir($dir_handle)) { // Note: checks for file, not dirs or symlinks if (is_file($file_piece)) { clearstatcache(); $file_lastmod = date("Y m d", filemtime($file_piece)); $file_list[$file_piece] = $file_lastmod; } } // After entire array is created, then we asort it as to // sort alphabetically by values (last mod dates) asort($file_list); // Print out array in fairly raw form :-) foreach ($file_list as $file_name => $file_lastmod) { print "<br>$file_name => $file_lastmod"; } closedir($dir_handle); Regards, Philip Olson .sig [ I am teachable ] [ and will work for money : http://www.cornado.com ] On Sun, 24 Dec 2000, Patrick Dunford wrote: > > I have a list of files that I want to sort by their last modified date in > descending order.
