Make a callable function out of this codes?

[ztealmax]

hi i have 2 pieces of code these 2:

First->

<?php

$path = "news"; // path to the dir you want to scan

foreach(glob("$path/*", GLOB_ONLYDIR) as $catdir) {
// catogories start
$catogories = ("".$catdir.".description");
$catfile = fopen($catogories, 'r') /*or die('Could not open file!')*/;
$catdata = fread($catfile, filesize($catogories)) /*or die('Could not read file!')*/;
fclose($catfile); 
$catdir = ereg_replace("news/", "", "$catdir");
echo "<a href='".$_SERVER['PHP_SELF']."?content=news'><b>".$catdir."</b></a>  ".$catdata."<br>";

}

?>

SECOND

<?php
  function in_dir ($file, $in_dir)
  {
      $dir    = realpath ($file);
      $in_dir = realpath ($in_dir);

      if (!is_dir ($file)) {
          $dir = dirname ($file);
      }

      do {
          if ($dir === $in_dir) {
              $is_in_dir = TRUE;
              break;
          }
      } while ($dir !== ($dir = dirname ($dir)));

      return (bool) @$is_in_dir;
  }
  $dir = $path;
echo $dir;
  $dh  = opendir($dir);
  while (false !== ($filename = readdir($dh))) 
{
   $pattern = '/\.news$/';
   if(preg_match($pattern,$filename))
   {
      /*    You can proceed because the file has the extension .zip       */
   $filename = ereg_replace($dir, "", "$filename");
  $filename = ereg_replace(".news", "", "$filename");
echo "<a href='?content=read&contents=".$dir."".$filename.".news'>" . $filename . "</a><br>";
   }
}

?>

 

 

this bit from first code

echo "<a href='".$_SERVER['PHP_SELF']."?content=news'><b>".$catdir."</b></a>  ".$catdata."<br>";

would be nice to make it an clickable function instead so i incorporate SECOND piece of code in to the first, but im not sure how to make a php function

 

What i need it to do is

 

first code scans folder and show all dirs as clickable links (complete and it works)

second piece of code scan subfolder and makes clickable links so function call should be something like:

 

echo "<a href=' CALL THE FUNCTION '><b>".$catdir."</b></a>  ".$catdata."<br>";

 

DOes this make any sence?

 

//Cheers
