pg_result_status — Get status of query result
pg_result_status() returns the status of the PgSql\Result instance, or the PostgreSQL command completion tag associated with the result
resultПримірник PgSql\Result, якого повертає одна з функцій pg_query(), pg_query_params() або pg_execute() (серед інших).
mode
Either PGSQL_STATUS_LONG to return the numeric status
of the result, or PGSQL_STATUS_STRING
to return the command tag of the result.
If not specified, PGSQL_STATUS_LONG is the default.
Possible return values are PGSQL_EMPTY_QUERY,
PGSQL_COMMAND_OK, PGSQL_TUPLES_OK, PGSQL_TUPLES_CHUNK, PGSQL_COPY_OUT,
PGSQL_COPY_IN, PGSQL_BAD_RESPONSE, PGSQL_NONFATAL_ERROR and
PGSQL_FATAL_ERROR if PGSQL_STATUS_LONG is
specified. Otherwise, a string containing the PostgreSQL command tag is returned.

Приклад #1 pg_result_status() example
<?php
// Connect to the database
$conn = pg_pconnect("dbname=publisher");
// Execute a COPY
$result = pg_query($conn, "COPY authors FROM STDIN;");
// Get the result status
$status = pg_result_status($result);
// Determine status
if ($status == PGSQL_COPY_IN)
echo "Copy began.";
else
echo "Copy failed.";
?>Поданий вище приклад виведе:
Copy began.
0 = PGSQL_EMPTY_QUERY
1 = PGSQL_COMMAND_OK
2 = PGSQL_TUPLES_OK
3 = PGSQL_COPY_TO
4 = PGSQL_COPY_FROM
5 = PGSQL_BAD_RESPONSE
6 = PGSQL_NONFATAL_ERROR
7 = PGSQL_FATAL_ERRORThis 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 example
if(($PGSTAT == 1) || ($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 fitThe 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.html
Therefore you cannot use this function to check if this query produced a notice.
