Need help with arrays

[xanikseo]

I'm a bit of a n00b when it comes to PHP, anyway, I am in process of making a website about Gaming News, and I decided to put all of my different news stories into different .txt files on a different directory. I have everything done fine except one thing: my news pieces are shown in the alphabetical order of the .txt filenames. That means that the latest story could be on page 53 or whatever. I have tried making codes that shows the news in the order of the creation/modification date of the .txt file.

Here is what I tried:

<?php

function returnfiles($dirname="docs/") {
   $pattern="\.(txt)$";
   $files = array();
   $fileloopcounter=0;
   if($handle = opendir($dirname)) 
       {
       while(false !== ($file = readdir($handle)))
               {
               if(eregi($pattern, $file)){
         $filedate=filemtime($dirname.$file);
                   $files[] = array($file, $filedate);
                 $fileloopcounter++;
               }
       }

       closedir($handle);
   }
   return($files);
}

function DateCmp($a, $b)
{
  return ($a[1] < $b[1]) ? -1 : 0;
}

function SortByDate($files)
{
  usort($files, 'DateCmp');
}

$files = returnfiles($dirname="docs/");
SortByDate($files);
echo '<ol>';
foreach ($files as $file => $val)
{
  echo '<li>', $val, '</li>';
}
echo '</ol>';
?>

And then I just get this when I open the file on a browser:



Can someone please help me with my problem?

Thanks in advance .

  echo '<li>', $val[0], '</li>';

[xanikseo]

Ah . Thank you very much . How could I put the result in reverse order?

[Twey]

function DateCmp($a, $b)
{
  return !($a[1] < $b[1]) ? -1 : 0;
}

[xanikseo]

function DateCmp($a, $b)
{
  return !($a[1] < $b[1]) ? -1 : 0;
}

Doesn't work... Strange...

[Twey]

Really? Hm. Try:

function DateCmp($a, $b)
{
  return ($a[1] > $b[1]) ? -1 : 0;
}

[xanikseo]

Still the same thing...

[Twey]

Paste here (in [code] tags) the output when using all the last three code blocks I posted.

[xanikseo]

The output is exactly the same as when you first fixed the code. All the files are listed in order of when they were modified, except all of the codes show the output with the newly modified files at the bottom.

there's probly an easier way, but you could just create a new loop that reverses after the fact... Or just start a variable and count down.
Then again, I'm sure Twey's method is easier and will work once you figure out what the issue is.
