When is the FALSE constant not False?  

$nResult = odbc_autocommit ($odbcConnection, FALSE)
if ( $nResult != FALSE )
  echo "ERROR: Unable to turn off commits!";

The above code worked most of the time, but sporatically reported an "ERROR:..." condition.   I tried changing "FALSE" to "False", but saw the same behavior.  

I am using the ISAPI DLL.   Perhaps there is a re-entrancy problem?   It works fine for a while after I restart IIS.

For now, I switched my code to use 0 (zero) and 1 (one) everywhere, instead of FALSE and TRUE.   This seems to have fixed the problem.

Steve

Try using !== instead of !=. != is numeric compare.
