array declared in one function, populated in nested function, remains blank

.everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty,.everyoneloves__bot-mid-leaderboard:empty{ height:90px;width:728px;box-sizing:border-box;
}

I've written the below function, but fileList is blank when echoed out.
Any ideas why this might be happening? and how to fix it?

function testing($dir){

echo $dir;

$fileList=array();



    function recursiveScan($dir) {



        $tree = glob(rtrim($dir, '/') . '/*');

        if (is_array($tree)) {

            foreach($tree as $file) {

                if (is_dir($file)) {

                    echo $file . '('.filemtime($file).')'.'<br/>';

                    recursiveScan($file);

                    $fileList[date('YmdHis',filemtime($file))]=$file;

                } elseif (is_file($file)) {

                    echo $file . '('.filemtime($file).')'.'<br/>';

                    $fileList[date('YmdHis',filemtime($file))]=$file;



                }

            }

        ?>

<pre>

<?php print_r($fileList);?>

</pre>

<?php   



        }



    }

}

EDIT:

If I move the print_r bit of the code below up a few } then it outputs... but I want to output it once all directories have been searched through.

function recursiveScan($dir) {



        $tree = glob(rtrim($dir, '/') . '/*');

        if (is_array($tree)) {

            foreach($tree as $file) {

                if (is_dir($file)) {

                    echo $file . '('.filemtime($file).')'.'<br/>';

                    recursiveScan($file);

                    $fileList[date('YmdHis',filemtime($file))]=$file;

                } elseif (is_file($file)) {

You have global $dir and $dir as a function parameter. Change the second one to another name.

I think better approach will be to use the return value to function argument to get the results. Consider the following function:

function recursiveScan($dir, $fileList) {

        $tree = glob(rtrim($dir, '/') . '/*');

        if (is_array($tree)) {

            foreach($tree as $file) {

                if (is_dir($file)) {

                    $fileList = recursiveScan($file, $fileList);

                } elseif (is_file($file)) {

                    $fileList[date('YmdHis',filemtime($file))]=$file;

                }

            }

        }

        return $fileList;

}

Now you can trigger the first call by doing something like:

$dir = "/"; // or from argument

$fileList = recursiveScan($dir, array());

After that, the $fileList will contain list of the files
