Question

我正在做两件事：

显示本地驱动器和
在单击时显示该目录中文件夹的内容文件夹名称。

我从下面的代码中获取目录列表，但是我无法使用这些文件来获取路径以及要显示其内容的文件名。

在这里，我从$path内的createDir()获取路径，从createDir()函数中的队列数组获取文件名。

有人可以帮助我将整个路径和文件名一起放入一个变量中，我可以在函数外部使用该变量来显示内容吗？

获取目录列表：

$path = "ggadmin/production/images/";

function createDir($path = '.')
{   
    if ($handle = opendir($path)) 
    {
        echo "<ul id='image'>";

        while (false !== ($file = readdir($handle))) 
        {
            $queue[]='';
            if (is_dir($path.$file) && $file != '.' && $file != '..')
                printSubDir($file, $path, $queue);
            elseif ($file != '.' && $file !='..')
                $queue[] = $file;
        }
        global $file;
        global $data;
        $file1 = implode(',',$queue);
        $file2 = explode(',', $file1);
        $data = var_export($path.$file1);
        /* eval('$data1 = ' . $data);*/

        printQueue($queue, $path);
        echo "</ul>";
    }
}

function printQueue($queue, $path)
{
    foreach ($queue as $file) 
    {
        printFile($file, $path);
    } 
}

function printFile($file, $path)
{
    echo  "<li><a href=\"".$path.$file."\">$file</a></li>";
}        

function printSubDir($dir, $path)
{       
    global $data1;
    echo "<li><a href=test1.php?data=$data1><span class=\"toggle\">$dir</span></a>";
    createDir($path.$dir."/");
    echo "</li>";

    /* global $image = createDir($path.$dir."/");*/
}

createDir($path);
global $path;
var_dump($path);

Answer 2

谢谢，我按照以下方式整理了答案。

由于我的目录列表正确显示了上述代码。我没有从两个函数中获取参数，而是对printSubDir($dir, $path)函数进行了如下修改

function printSubDir($dir, $path)
    {       
        global $data;
        $data = $path.''.$dir;
                echo "<li><a href='test1.php?data=$data'><span 
 class=\"toggle\">$dir</span></a>";
        createDir($path.$dir."/");
        echo "</li>";
    }

从上面的代码中，我得到（$ _GET ['data']）test1.php中的数据值，并显示了test1.php本身的所有内容。
