PHP 5.3.1 not loading php_oci8.dll on Windows

Question

I'm trying to load the oracle extension on php but im having the error:

Warning: PHP Startup: Unable to load dynamic library 'D:\Program Files\xampp\php\ext\php_oci8.dll' - The specified procedure could not be found. in Unknown on line 0

I have done so far:

1. Included on windows path the the fullpath of oracle instant client
2. on php.ini, the extension_dir is pointing to the right place
3. on php.ini extension=php_oci8.dll is ok
4. restarted the apache, and nothing works.

Answer 1

Problem solved by copying the files orannzsbb11.dll , oci.dll and oraociei11.dll to c:\windows\system32

Answer 2

I solved this problem by adding "C:\Program Files (x86)\PHP\v5.3\ext" to my Windows PATH environment variable. You'll just have to remember to change the path if you upgrade PHP. I think this is better than copying dlls which could lead to issues down the road if you end up with multiple dlls with different versions on the same machine.

You will need to download Oracle Instant client from this hyperlink http://www.oracle.com/technetwork/topics/winsoft-085727.html . Add the path to the instant client on the user environment vriables and the system variables.
