sort files by date in PHP

Question

I currently have an index.php file which allows me to output the list of files inside the same directory, the output shows the names then I used filemtime() function to show

Answer 1

I use your exact proposed code with only some few additional lines. The idea is more or less the same of the one proposed by @elias, but in this solution there cannot be conflicts on the keys since each file in the directory has a different filename and so adding it to the key solves the conflicts. The first part of the key is the datetime string formatted in a manner such that I can lexicographically compare two of them.

if ($handle = opendir('.')) {
    $result = array();
    while (false !== ($file = readdir($handle))) {
        if ($file != "." && $file != "..") {
            $lastModified = date('F d Y, H:i:s',filemtime($file));
            if(strlen($file)-strpos($file,".swf")== 4){
                $result [date('Y-m-d H:i:s',filemtime($file)).$file] =
                    "$file$lastModified";
            }
        }
    }
    closedir($handle);
    krsort($result);
    echo implode('', $result);
}
