How do I populate an array with a directory listing.

Question

I have a web site that has its photos updated by another person using a content management system that I have written. As Dreamweaver does not know about these extra photos, if I try to
syncronise the site on my machine for backup purposes, Dreamweaver downloads all 5000+ photos, and this can take upwards of 12 hours if there are no breaks in the connection.
So I am trying to write a page that creates an array of the existing files on the remote site. It will then do the same on my local site, and by comparing the arrays, will make a list of the new files, and then download these, which will save a lot of time and bandwith charges.
First I have to read the directory list, using the code below which reads and echos it on screen.
However, I cannot work out how to populate the required array.
<?php
    try
    {          /***photo directory ***/
        $it = new directoryIterator('../web/thumbs');
        while( $it->valid())
              /*** echo if not a dot directory ***/
            if( !$it->isDot() )
/**** Array creation code needs to go here I think.***/
echo $it->current()."<br />";
     /*** move to the next element ***/
                  $it->next();
    catch(Exception $e)
        /*** echo the error message ***/
        echo $e->getMessage();
?>
This creates a list of files and displays it on the page.
How do I store it in an array?

Although not the solution you were looking for, consider the following:
Click the icon in DW for "Expand to show local and remote sites."  Arrange the remote image directory by "Modified date," Then select all the recent images and GET them.
I find the above method good enough for occassional synchronization. I also simply ignore broken image links on the testing system.
If the above is not a solid enough solution, perhaps someone else will write your array function for you. I don't have the time.
