Building & Sorting an Array

[Cynthia_Blue]

I have this snippet of code I'm attempting, it is supposed to loop through a subdirectory and list all the files therein. I also want it to list the files in date order, newest first. I want the date, filename, and file size all listed in the display.

Sooo..from various tutorials on the web this is what I have come up with (no the sort isn't working yet):

$dirpath = getcwd() . "/minutes/";
$dir = opendir($dirpath);
$files = array();
$ar2 = array();
$arrC = 0;
$arrC2 = 0;
$arrC3 = 0;
while ($file = readdir($dir)) {
   $localpath = $dirpath.$file;
   if (is_file($localpath)) {
       $uts=filemtime($localpath); 
       $filedate = date ('m/d/Y g:i:s A', $uts); 
       $filebig = filesize($localpath);
       $ar2[$arrC][$arrC2][$arrC3] = $filedate;
       $arrC2++;
       $ar2[$arrC][$arrC2][$arrC3] = $file;
       $arrC3++;
       $ar2[$arrC][$arrC2][$arrC3] = $filebig;
       $key = filemtime($localpath).md5($file);
       $files[$key] = $file;
   $arrC++;
   $arrC2++;
   $arrC3++;
   }
}

ksort($ar2);
foreach ($ar2 as $x1) {
   echo "<tr>";
   foreach ($x1 as $y2) {
      foreach ($y2 as $x3) {
         echo "<td width=150> $x3 </td>";
      }
   }
   echo "</tr>";
}
closedir($dir);

I am very, very new to PHP and would love and appreciate some help. Is there a better way to do this? The sort works on the array's key... but, not sure how it'd work. The sort doesn't work here. Also note, there is some extra array stuff in there that's not quite used but I didn't want to take out yet. 🙂

Thanks. 🙂

Okay this works better. And the sort works too. However, I want to list a "kb" after the file size, and have the file name be a link. Which causes a problem in the display. 🙂

$dirpath = getcwd() . "/minutes/";
$dir = opendir($dirpath);
$ar2 = array();
$arrC = 0;
$arrC2 = 0;
$arrC3 = 0;
while ($file = readdir($dir)) {
   $localpath = $dirpath.$file;
   if (is_file($localpath)) {
       $key = filemtime($localpath).md5($file);
       $uts=filemtime($localpath); 
       $filedate = date ('m/d/Y g:i:s A', $uts); 
       $filebig = filesize($localpath);
       $ar2[$key][$arrC][$arrC2][$arrC3] = $filedate;
       $arrC3++;
       $ar2[$key][$arrC][$arrC2][$arrC3] = $file;
       $arrC3++;
       $ar2[$key][$arrC][$arrC2][$arrC3] = $filebig;
       $arrC++;
       $arrC2 = 0;
       $arrC3 = 0;

   }
}

krsort($ar2);
foreach ($ar2 as $x1) {
   echo "<tr>";
   foreach ($x1 as $a2) {
   	foreach ($a2 as $y2) {
           foreach ($y2 as $x3) {
             echo "<td width=150> $x3 </td>";
           }
       }
   }
   echo "</tr>";
}
closedir($dir);

Here is my final code. I would love input on whether there is a better way to do this or not.

Oh.. it's not totally final. I want to give an admin the option of deleting files. Hrm... I hope I can incorporate that.

$dirpath = getcwd() . "/minutes/";
$dir = opendir($dirpath);
$ar2 = array();
$arrC = 0;
$arrC2 = 0;
$arrC3 = 0;
while ($file = readdir($dir)) {
   $localpath = $dirpath.$file;
   if (is_file($localpath)) {
       $key = filemtime($localpath).md5($file);
       $uts=filemtime($localpath); // Get the filetime for sorting
       $filedate = date ('F d, Y g:i A', $uts); // Format filetime for display
       $filebig = filesize($localpath); // Get the file size for display
       // Plop the values into an array for sorting later
       $ar2[$key][$arrC][$arrC2][$arrC3] = $filedate;
       $arrC3++;
       $ar2[$key][$arrC][$arrC2][$arrC3] = $file;
       $arrC3++;
       $ar2[$key][$arrC][$arrC2][$arrC3] = $filebig;
       $arrC++;
       $arrC2 = 0;
       $arrC3 = 0;

   }
}

   	foreach ($a2 as $y2) {
           foreach ($y2 as $x3) {
             if ($countcells == 1) { // File date
               echo "<td class=mins width=200>$x3</td>";
             }
             elseif ($countcells == 2) { // File Name
               echo "<td class=mins width=150> <a href=minutes/$x3>$x3</a></td>";
