Performance tip:



Beware of the performance penalty involved with unchecked use of logging options. In my case, although I was using the buffered cursor, sqlsrv_fetch_array was running too slowly. The solution was to remove my lavish use of those configuration options (using both SQLSRV_LOG_SYSTEM_ALL and SQLSRV_LOG_SEVERITY_ALL).
