int pg_affected_rows(resource $result)
pg_affected_rows() returns the number of tuples (instances/records/rows) affected by INSERT, UPDATE, and DELETE queries.
Since PostgreSQL 9.0 and above, the server returns the number of SELECTed rows. Older PostgreSQL return 0 for SELECT.
This function used to be called pg_cmdtuples().
The number of rows affected by the query. If no tuple is affected, it will return 0.
- resource $result: PostgreSQL query result resource, returned by pg_query(), pg_query_params() or pg_execute() (among others).
Example #1 pg_affected_rows() example
$result = pg_query($conn, "INSERT INTO authors VALUES ('Orwell', 2002, 'Animal Farm')");
$cmdtuples = pg_affected_rows($result);
echo $cmdtuples . " tuples are affected.\n";
The above example will output:
1 tuples are affected.
