How to get parameter values from two different functions into a another variable in a different function?

Question

I am working on two things:

displaying directory list from my local drive and
displaying the contents of folder from that directory when clicked on folder name.

I am getting the directory list from the following code, but I am unable to get the path along with the file name which i want to display the contents by using those.

Here I am getting path from $path, which is inside createDir() and file name from queue array which is also in createDir() function.

Can anyone help me to get the whole path along with the filename in to a variable which I can use outside of the function for displaying contents?

Getting Directory list:

$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);

I am getting the path value from function printSubDir($dir,$path) which i assigned to a variable $data (inside function) can any one tell me how to get and use variable $data in <img> tag which is outside of loop to display contents? — SivaJyothiG

Thanks, can you tell me how to refresh the particular <div> tag when clicked on the anchor tag? As i am trying that one as follows I am unable to pass the ur parameters which i defined with in a function.
<a href='#' id='btn_click'>$dir</a> JQuery: $(document).ready(function() { $('#btn_click').on('click', function() { var url = 'test1.php?data=$data'; $('#display').load(url + ' #display1'); }); });
Can we speak in Skype? I did not understand clearly what solution you want to get, but I think I'm able to help you. And then post here for others the solution we did.
Sorry i am unable to do that but i will explain you clearly here. As i am getting the list of directories on left side div tag and displaying their content on right side div tag(when clicked on folder name), while doing this process the whole page is loading each time when i clicked different folders. As i have huge amount of data the page loading time is more, so i want to reduce the page loading time by making only right side div reloading every time but not the whole page. I want to how to do this with my code as i am passing url with in a function. Can you suggest me the right way?
There are a lot of ways to do so. e.g. ReactJS+some backend. And a question: Do you want use a real folder tree, or some DB to emitate real folder tree?

Thanks, i sorted out my answer in the following way.

As my directory list is displaying properly with the above mentioned code. Rather than getting the parameters from two functions, I modified printSubDir($dir, $path) function as follows

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>";
    }

From the above code i get ($_GET['data']) the data value in test1.php and displayed all contents test1.php itself.
