The company I work for currently uses some basic functions to abstract the OCI libraries as a means for DB connectivity. We\'re considering switching to PHP\'s PDO object,
May be I'm too late to the party .. just thought to add some value to the discussion. I am experienced in OCI8 and OCI8_11 extension and have done some extensive workload using stored procedures/packages, CLOB/BLOB's and XML I never had to run out of options .. further it seems very reliable and can handle extensive loads and I have even used once for an ETL(Extract Transform Load) applications to handle heavy workloads... also believe oci8 is the widely used extension .. than pdo ..
