Finding the newest file

[pea_1]

Hello, i'm trying to find the last modified file in a set of directories but i can't figure out how to compare the file date, pick the newest date and then displaying the file name. I have this, but i'm not sure where to go or if it's even the way to do it.

 

Thanks, Peter.

 

<?php

//put each dir into an array

$dir = "../forum/";
$filearray = array();

if (is_dir($dir)) {
   if ($dh = opendir($dir)) {
       while (($file = readdir($dh)) !== false) {
   
   if(preg_match("/forumposts_/", $file)){
   array_push($filearray, "$file");
	   }
       }
       closedir($dh);
   }
}

//echo each file and it's last modify date

foreach($filearray as $filer){

$filer = "../forum/$filer";


if ($handle = opendir($filer)) {
   while (false !== ($file = readdir($handle))) {
       if (preg_match("/.php/", $file)) {
   
   
   $file = "$filer/$file";
  
   
           echo "$file".date ("F d Y H:i:s.", filemtime($file))."<br>";
	   
       }
   }
   closedir($handle);
}

}
?>

Ah thanks. I think i can use the script from this comment:

 

Neat little script that will give you a list of all modified files in a certain folder after a certain date:

 

$filelist = Array();

$filelist = list_dir("d:\\my_folder");

for($i=0;$i<count($filelist);$i++){

  $test = Array();

  $test = explode("/",date("m/d/Y",filemtime($filelist[$i])));

//example of files that are later then

//06/17/2002

  if(($test[2] > 2001) && ($test[1] > 16) && ($test[0] > 5)){

      echo $filelist[$i]."\r\n";

  }

  clearstatcache();

}

function list_dir($dn){

  if($dn[strlen($dn)-1] != '\\') $dn.='\\';

  static $ra = array();

  $handle = opendir($dn);

  while($fn = readdir($handle)){

      if($fn == '.' || $fn == '..') continue;

      if(is_dir($dn.$fn)) list_dir($dn.$fn.'\\');

      else $ra[] = $dn.$fn;

  }

  closedir($handle);

  return $ra;

}

Now i can't find anything on sorting by date.. You might be able to make your own sorter, not that i know how, but even then it must be a huge script. Is there any other way?

i'd write you an example, but i simply do not have the time. but to explain what i'd do, is write something like a foreach loop that checks the last time each file was accessed. then, pump each file into the correct index in order. so if the first file it reads was accessed 3rd, it would store it in the 3rd index of the array. does that make sense?
