Answer 1

The php function dir will help you.

http://php.net/manual/en/class.dir.php

There is an example in the notes of the docs (by sojka at online-forum dot net) that shows doing this, which I have included below...

<?php
public static function getTreeFolders($sRootPath = UPLOAD_PATH_PROJECT, $iDepth = 0) {
      $iDepth++;
      $aDirs = array();
      $oDir = dir($sRootPath);
      while(($sDir = $oDir->read()) !== false) {
        if($sDir != '.' && $sDir != '..' && is_dir($sRootPath.$sDir)) {
          $aDirs[$iDepth]['sName'][] = $sDir;
          $aDirs[$iDepth]['aSub'][]  = self::getTreeFolders($sRootPath.$sDir.'/',$iDepth);
        }
      }
      $oDir->close();
      return empty($aDirs) ? false : $aDirs;
}
?>

There are lots of other similar examples from other people on the same page, so find one that you like and go from there...

You could iterate trough the dirctory using a RecursiveDirectoryIterator. Look at this:

$search_query = "test";
$directory = new RecursiveDirectoryIterator('/path/');
$iterator = new RecursiveIteratorIterator($directory);
$result = new RegexIterator($iterator, '/^.+\'.$search_query.'$/i', RecursiveRegexIterator::GET_MATCH);

Then (array) $result should usually contain all filenames in which 'test' was found under '/path/'.

Hope it helps ;)
