pg_fetch_assoc — Fetch a row as an associative array
$result
[, int $row
] ) : arraypg_fetch_assoc() returns an associative array that corresponds to the fetched row (records).
pg_fetch_assoc() is equivalent to calling
pg_fetch_array() with PGSQL_ASSOC as the
optional third parameter. It only returns an associative array.
If you need the numeric indices, use
pg_fetch_row().

of rows in the set, there are no more rows, or on any other error.
