pg_send_query

 bool pg_send_query ( resource $connection , string $query ) 

説明

pg_send_query() sends a query or queries asynchronously to the connection. Unlike pg_query(), it can send multiple queries at once to PostgreSQL and get the results one by one using pg_get_result(). Script execution is not blocked while the queries are executing. Use pg_connection_busy() to check if the connection is busy (i.e. the query is executing). Queries may be cancelled using pg_cancel_query(). Although the user can send multiple queries at once, multiple queries cannot be sent over a busy connection. If a query is sent while the connection is busy, it waits until the last query is finished and discards all its results.

戻り値

Returns TRUE on success or FALSE on failure. Use pg_get_result() to determine the query result.
