PHP Manual: pg_result

Description

function pg_result_error(PgSql\Result $result): string|false

pg_result_error() returns any error message associated with the result instance. Therefore, the user has a better chance of getting the correct error message than with pg_last_error().

The function pg_result_error_field() can give much greater detail on result errors than pg_result_error().

Because pg_query() returns false if the query fails, you must use pg_send_query() and pg_get_result() to get the result handle.

Parameters

result: An PgSql\Result instance, returned by pg_query(), pg_query_params() or pg_execute()(among others).

Return Values

Returns a string. Returns empty string if there is no error. If there is an error associated with the result parameter, returns false.

Changelog

Version	Description
8.1.0	The `result` parameter expects an PgSql\Result instance now; previously, a resource was expected.
