pleasehelp ! arrays :(

[electronish]

Using the following code  I am able to get the files and folders , But  i cannot access arrays . THis script gives me the files and their info like mtime , size etc But  I want to comapre the timestamps to check for a new file and then copy it to different folder. How can  I use the following code to compare the mtime between a file and the file previous to it.  ?


[code]<?php

$dir = chdir('D:\MYvideos');

function recur_dir($dir)
{
$dirlist = opendir($dir);
while ($file = readdir ($dirlist))
{
if ($file != '.' && $file != '..')
{
$newpath = $dir.'/'.$file;
$level = explode('/',$newpath);
if (is_dir($newpath))
{
$mod_array[] = array(
'level'=>count($level)-1,
'path'=>$newpath,
'name'=>end($level),
'kind'=>'dir',
'mod_time'=>filemtime($newpath),
'content'=>recur_dir($newpath));
}else{

$mod_array[] = array(
'level'=>count($level)-1,
'path'=>$newpath,
'name'=>end($level),
'kind'=>'file',
'mod_time'=>filemtime($newpath),
'size'=>filesize($newpath));
counter();
  }
}
}
closedir($dirlist);
return $mod_array;
}
function counter()
{
global $count;
$count = $count+1;
}
echo '<pre>';
print_r(recur_dir('.'));
echo '</pre>';
print "total number of files are $count";
