如果foreach循环内的条件（scanDirectory函数）

Question

我试图在foreach循环中使用php条件，但我遇到了一些困难。我抬头看着其他线程处理，但找不到解决方案/解释适用于我的代码。那就是：

<?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); 
?> 

我想这样取而代之的是被回显变量$文件夹会比另一个变量的条件来代替行echo "$folder<br />";才回到进入死循环，这样：

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

基本上我的代码的目的是为了特定的剧目与保留剧目的用户目前在比较，如果有一个匹配，那么一些HTML将被显示，但我想我没有正确的做法。

任何建议表示赞赏！

感谢您的帮助

给当前目录作为参数传递给函数并把它作为你通过所有文件夹。

<?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); 
?>
