Scan a directory and move or copy all files to a date-structured directory

import.php

<?php
/*
This script will scan the directory you specify and move or copy 
all files within it and its subdirectories. The files will be moved 
to a subdirectory of the location where the script is, based on 
either it's creation date or if the file contains exif data, the 
date the photo was taken.


Call this script like so:

php import.php --dry-run --remove /home/me/Pictures


Flags:

--dry-run
	Run the script but don't actually remove or copy any files

--quiet
	Suppress all output expect errors

--remove
	Remove the source files and folders after copying

	Note: With this flag, any subdirectories in the source won't be 
	removed on the first run, but will be if you rin it again. This 
	is to prevent errors where files are in the process of being 
	copied or synchronized while the script is being run.
