     Oracle 8 database and logs on.  The optional third parameter can
     either contain the name of the local Oracle instance or the name
     of the entry in tnsnames.ora to which you want to connect.  If
     the optional third parameter is not specified, PHP uses the
     environment variables ORACLE_SID (Oracle instance) or TWO_TASK
     (tnsnames.ora) to determine which database to connect to.
