It is my understanding that the PHP gods dropped support as of ver. 5.3. The ntwdblib.dll is also missing for either php.ini file (Apache or PHP). But it is present in 5.2.x versions (I use both PHP versions).
Speaking of MSSQL, I am in the process of setting this up for ver. 5.2.5. Does anybody know what the correct installation procedures are to do this?
