Hey,
I'm French so i'll try to explain in my best english.
I had the same problem. And i solved it.
In fact i change the dll because the one which php install give us is not compatible.
I choose the one which is provides with wampserver 2.0i.
php_oci8_11g.dll
with instantclient_11_1g
Next i'll create environnement variables
NLS_LANG=FRENCH_FRANCE.WE8ISO8859P15
TNS_ADMIN=d:\oracle
and in path variable add the way to the instantclient11_1
D:\oracle\instantclient_11_1
Then i restart the server and lucky all services start and run perfectly.
