Con-way XML Sample Code for PHP 5 - Image Retrieval interface
This code has been tested on PHP 5.04 using the SimpleXML Extension
-----------------
TODO:
* replace the USERNAME and PASSWORD String values below
with your Con-way username and password
* replace PRONUMBER strings below with your own 9-digit PRO Numbers
* update $imageDir with the location to which you want to write
* the image files on your webserver
* update $imageUrl with the URL to access the files
NOTE: you must have the cURL libraries installed with PHP on your server--
If you need them, see your System Administrator, who can get then at
http://curl.haxx.se/download.html
