## 例

`

     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.
