Well, I need this for 2 purposes.
I dont want to just know for myself, but I want the code to be aware of its environment, and do whatever is most efficient.
For example, are the mssql functions available, no? ok then what about odbc functuons? ect ect. I dont really want to parse the phpinfo() for each of these 🙁
The other is, for a site like zend.com's function tables, you mean to tell me that somebody actually hand coded each link, ect for all those function listings?
