Okay, I'm a ColdFusion programmer who who spent the past 5 years as the sole programmer on our organization's main website.
We have hired other junior programmers for specific project-related websites. Some of them work in PHP and one of our key project sites has moved over to the LAMP platform.
The system we've created in ColdFusion MX not only runs our Website, but runs parts of our Intranet, a backend home-grown CMS, online tracking and data analysis tools, and several other applications. Plus we have a few project sites coded in CFMX. We use a lot of stored procedures in our SQL Server 2000 database and use cfloops in much of our output.
Now, there is a groundswell from the PHP programmers to move our site over to the LAMP platform as we consider revising our site and adding a true CMS. Up to this point, I've been open to potentially developing a migration path to PHP, but right now I'm under the gun to get a site facelift/revision done by the end of September 2006 AND a CMS tool in place to support some of the new features in this site facelift/revision. I've been looking at keeping things in ColdFusion/SQL Server 2000 and adding CommonSpot CMS (which I understand supports ColdFusion and PHP) with FuseTalk (for the forum/blogging elements).
However, there is still push for me to move from CFMX/SQL Server to PHP/MySQL.
I'm sending this to the PHP folks because I need to hear your side of the argument ...
