php includes === Dreamweaver library items

Hi, Has anyone experience of using Dreamweaver library item files (.lbi)s as php includes? We've got a standard header and footer to go across all pages on a site with the navigation etc. We want both the designers, (using Dreamweaver), and the php programmers to have access to these includes, so that the Dreamweavers can view the pages automatically with the headers/footers shown, and the programmers can still maintain the pages and includes without Dreamweaver. I don't fully understand how Dreamweaver library files work, so I guess my questions are : a) Can you use a url for a Dreamweaver libary file rather than using a local file so we can all share a single master copy? b) Can we tell Dreamweaver to include the libary file's html when previewing but exclude it when saving, so we don't end up with the library code twice, once embedded by Dreamweaver on the save and once included by php at execution? (I insist on the live page using the master version as I'm not prepared to trust the Dreamweavers to rebuild the pages when the library files change!) I guess I've got workarounds if the answers to these prove negative. For a) I can bully the Dreamweavers into keeping the master/local copies in step, and for b) I guess I can get the php to strip out the Dreamweaver copy of the library code at execution with a little bit of spoofing of Dreamweaver about where php starts and ends i.e. something like.... <?php turn_into_an_include(<<<ENDLIBRARY ?> dreamweaver library item tags and text <!-- ENDLIBRARY ); //--><?php ?> where turn_into_an_include is a function which just finds the library file name in the passed string of library code and includes it from the appropriate server directory. Of course, this is a bit clumsy, any better suggestions? Many thanks, George ?> c) In the worst case I guess, we can live with local and master copies of library files and remind the Dreamweavers to always update the master when they make changes get the php code to strip out the embedded library file html at execution time and replace it with an appropriate include statement of the server copy. I've got an idea how to do this by as anyone else tried this?
