Recursive file processing in PHP?

[Mong]

Hi,

I've never really got into handling files in PHP, but now I'd like too. I've set myself a simple task: Have multiple nested directories, each with multiple text files in. Then recurse through each directory getting the contents of each text file (a single word) and put the words into an array.

I've got no trouble reading a single file into an array, but have got stuck when trying to recurse a directory.

Anybody ever done stuff like this before?

here is some info about directories
youll probably need readdir(), and is_dir() (thats here)

I've had to recurse directories before in PHP.
I made a photo album script so you could just dump photos to a specific folder (and subfolders within that folder) over FTP and then the index script would generate the albums (reprocess images for thumbnails, add alt text etc) on the fly.
I pretty much had to do what wu_trax has suggested.

<?php
  function traverse_dir($dir,$suffix='') {
    $ret = array();
    if($hnd = opendir($dir)) {
      while(false !== ($f = readdir($hnd))) {
        if(is_dir($dir.'/'.$f)) {
          if ($f!='.' && $f!='..') {
            $tArr = traverse_dir($dir.'/'.$f);
            foreach($tArr as $k => $v) {
              $ret[$k] = $v;
            }
          }
        }
        elseif(is_readable($dir.'/'.$f) && preg_match("/$suffix$/",$f)) {
          $ret["$dir/$f"] = file_get_contents($dir.'/'.$f);
        }
      }
      closedir($hnd);
    }
    return $ret;
  }

  $words = traverse_dir('/home/tom/wibble','\.wibble');
  print_r($words);
?>

> $ php traverse.php
Array
(
    [/home/tom/wibble/blah/1/2.wibble] => sdfsfme
    [/home/tom/wibble/blah/2/2.wibble] => sdfs34234fme
    [/home/tom/wibble/1.wibble] => mememe
    [/home/tom/wibble/2.wibble] => memedsfme
)

MT uses spaces to format his code.

using tabs is just WRONG WRONG WRONG
tr "\t" ' '

[pablissimo]

My Textpad's set to use two-spaces in place of a tab, what's so evil about that? =(
