I am using PHP 5.4.28 as downloaded from windows.php.net. I am using the threadsafe version. I have also tried 32bit and 64bit Windows7 and I get the same results.
I have installed the oracle instantclient and have set/created the following system variables: ORACLE_HOME, PATH and TNS_ADMIN. These variables are definitely pointing to the correct folder. I've also copied all the dll files that came with instantclient to system32.
I still cannot make the oci drivers to load.
some notes:
- extension_dir is properly set. I can load other modules like bz2
- oci/pdo_oci drivers are present in extension_dir
Thanks for the help
