working solution gets you $5 paypal

this is an auto delete script it is supposed to look at a files age and delete files older than 7 days old.. right now the script deletes everything regardless of age except htaccess...
if you can fix this to do delete only files older than 7 days old and leave the rest alone you will get $5 paypal for your working response...

thanks!

<?php
function delete_old_files($dir, $time_limit = 604800,$exclude=array()){ 
if(!$time_limit) $time_limit = 7*24*60*60; 
if ($df = opendir($dir)) {  
while (false !== ($file = readdir($df))) {
   if ($file != "." && $file != "..") {    
$last_modified = filemtime($file);       
 if((time()-$last_modified > $time_limit) && !in_array($file , $exclude)){     unlink($dir."/".$file);   
 }   
}  
}  closedir($df); 
}
}delete_old_files('gcd' , 604800 , array('.htaccess'));
delete_old_files('uploadedFiles' );
delete_old_files('temp' );
?>

Try:

       function delete_old_files($directory,$seconds_old,$exclude) {

                if( !$dirhandle = @opendir($directory) )
                        return;

                while( false !== ($filename = readdir($dirhandle)) ) {
                        if( $filename != "." && $filename != ".." ) 
                        {
                        if	(!in_array($filename , $exclude))
                        	{
                                $filename = $directory. "/". $filename;

                                if( @filemtime($filename) < (time()-$seconds_old) )
                                        @unlink($filename);
                                }
                        }
                }
        }
        delete_old_files('gcd' , 604800 , array('.htaccess'));
