If condition inside a foreach loop (scanDirectory function)

I'm trying to use a php condition inside a foreach loop but i'm having some difficulties. I looked up in the other threads dealing with that but couldn't find a solution/explanation to apply in my code. Here it is :

<?php
    $directory = $_SESSION['cwd'];              // current directory
    $user = $_SESSION['simple_auth']['username']; // get username
    $repository = gatorconf::get('repository');   // get base repertory of the file manager
    $userdir = $repository.DS.'user'.DS.$user;   // user's repertory

function scanDirectory($userdir = ''){
    $folders = glob($userdir . '/*' , GLOB_ONLYDIR);
    foreach($folders as $folder){
        echo "$folder<br />";      // line where i tried different things for my condition
        scanDirectory($folder);
    }
}
scanDirectory($userdir);
?>

I'm trying to replace the line echo "$folder<br />"; by a condition so that instead of being echo'd the variable $folder would be compared to another variable before going back into the loop, like this :

if ($folder == $directory) {
    echo "you have permissions on this folder";
}

Basically the purpose of my code is to compare specific repertories with the repertory the user is currently in, and if there is a match then some html will be displayed, but I think i don't have the right approach.

Any suggestions is appreciated !

Thanks for the help

Give the current directory as a parameter to the function and pass it on as you go through all folders.

<?php
$directory = $_SESSION['cwd'];              // current directory
$user = $_SESSION['simple_auth']['username']; // get username
$repository = gatorconf::get('repository');   // get base repertory of the file manager
$userdir = $repository.DS.'user'.DS.$user;   // user's repertory

function scanDirectory($userdir = '', $directory){
  $folders = glob($userdir . '/*' , GLOB_ONLYDIR);
  foreach($folders as $folder){
      if ($folder == $directory) {
          echo "you have permissions on this folder";
      }
      scanDirectory($folder, $directory);
  }
}

scanDirectory($userdir, $directory);
?>
