HOWTO for creating PHP extensions

Hi, Is there a HOWTO somewhere on creating PHP extensions, either through a dll or compiled in? The PHP online manual does not have enough info (that I could find), and the one bit of information I found refers to scripts and directories off of the PHP source tree that don't exist. I have an older program that has some legacy functions and custom database libraries that I would like to wrap into a PHP module and use directly, but I can't figure out how. I have looked at the mysql.c and have an idea, but I have too many questions that can't be answered by the info I have. The only other alternative would be to create some little C wrappers and use exec/system type calls to pull the data in, but this seems like much more work than necessary. Please, if anyone out there knows where I can find this, let me know!! (also, if the PHP people are reading this, please put more info about this on your web page, and keep up the good work!) -- Mark McCoy -- Cajun Brothers Technology, llc My views do not necessarily reflect the views of my employer. ------------------------------------------------------------------------ Proudly supporting the Free | "Linux _is_ user friendly, it just Software movement since 1996. | picks its friends very carefully." -------------------------------------------------------------------------
