Read Directory

**Phill Pafford** · 10-19-2006 03:58 PM

Hi here is my code to read the files in a directory, now I would like to only return the 25 most newly created files in ascending order. how can I do this?

Some of my directories can have 100's of files, but I only need the 25 newest files to display in ascending order.

Thanks for any help

Hi Phill

Here's one way that springs to mind.

Rather than directly outputting the $file and modified date, you could store the data in an array using the filemtime($file) as the key, and $file as the value. You could then sort the array using key based sorting (ksort : http://uk.php.net/manual/en/function.ksort.php or more likely krsort (reverse key sort) http://uk.php.net/manual/en/function.krsort.php ). Then just output the first 25 items in the array.

Hope this helps.

**Phill Pafford** · 10-20-2006 03:24 PM

Thanks for the advice, but its not going as planned

I changed the function to this, but I can not get the order to sort asc or desc

PHP Code:


function make_dir($dir, $proc, $openDir)

{

        $dir_cnt = 0;

        echo("<td valign=\"top\" nowrap>");

        echo("<fieldset><legend>$proc</legend>");

        echo("Location:<br><font color=\"green\">$dir</font><br><hr>");

        while(false !=($file= readdir($openDir)))

        {

                //Initialize the array

                $dir_arr = array();



                if(!preg_match('/^\./',$file))

                {

                        //echo "<font color=\"blue\">$file : </font>" . date ("F d Y H:i:s", filemtime($dir."/".$file)).'<br>';

                        $file_time = date ("mdYHis", filemtime($dir."/".$file));

                        $dir_arr[$file_time]="$file";

                }



                krsort($dir_arr);

                foreach ($dir_arr as $key => $val)

                {

                        echo("<font color=\"blue\">$val</font> = DATE: $key <br>");

                        $dir_cnt++;

                }



        }

        echo("File Count: $dir_cnt <br>");

        echo("</fieldset><br>");

        echo("</td>");

        echo("<td>&nbsp</td>");

}

Any other help would be great

It may be because you have mdYHis for the date format.

Change this so that it is year->month->day (YmdHis) and see how it goes.

**bokeh** · 10-21-2006 03:31 PM

PHP Code:


<?php



$directory = '.';



$handle = opendir($directory) or die('I could not open '.$directory);



while(false !== ($file = readdir($handle)))

{

    if(!preg_match('/^\./',$file))

    {

        $files[] = $file;

        $age[] = filemtime($directory.'/'.$file);

    }

}



closedir($handle);



array_multisort($age, SORT_NUMERIC, SORT_DESC, $files); 



foreach(array_slice($files, 0, 25) as $k => $v)

{

    echo '<p><b>'.$v.'</b> '.date('Y/m/d H:i:s', $age[$k]).'</p>';

}



?>
