pg_result_status

0 = PGSQL_EMPTY_QUERY1 = PGSQL_COMMAND_OK2 = PGSQL_TUPLES_OK3 = PGSQL_COPY_TO4 = PGSQL_COPY_FROM5 = PGSQL_BAD_RESPONSE6 = PGSQL_NONFATAL_ERROR7 = PGSQL_FATAL_ERROR

This function is useful it may not return a  full non fatal error but you want to see if the query completes anyway.example<?PHP//connect to pg database// create PGSQL$PGSTAT = pg_result_status($PGSQL);//defaults to long//And run it through a check for exampleif(($PGSTAT == 1) || ($PGSTAT == 2)){ // for query results;}else if(($PGSTAT == 3) || ($PGSTAT == 4)){ // for copy results;}if(($PGSTAT != 0) && ($PGSTAT != 5) && ($PGSTAT != 6) && ($PGSTAT != 7)){// your code;}else{ // $ERRORS codes;}// This is worked the best for me so far  I tried using // The command tag and I seem to still get an numeric result//example//$PGSTAT = pg_result_status($PGSQL, PGSQL_COMMAND_OK);// got something like tuples ok so I recommend just use default long?>or use what ever condition check you feel fit

The postgres docs say that PHP should never be able to return PGRES_NONFATAL_ERROR"A result of status PGRES_NONFATAL_ERROR will never be returned directly by PQexec or other query execution functions" http://www.postgresql.org/docs/current/static/libpq-exec.htmlTherefore you cannot use this function to check if this query produced a notice.

If on "accident" your program passes pg_result_status a variable that is NOT a actual pg resource, it will return an empty string.(This is important to know if you want to make sure a pg resource is "good" before attempting some operation on it).
