pg_get_result — Get asynchronous query result

Açıklama

pg_get_result(PgSql\Connection $connection): PgSql\Result|false

pg_get_result() gets an PgSql\Result instance from an asynchronous query executed by pg_send_query(), pg_send_query_params() or pg_send_execute().

pg_send_query() and the other asynchronous query functions can send multiple queries to a PostgreSQL server and pg_get_result() is used to get each query's results, one by one.
