pg_end_copy — 与 PostgreSQL 后端同步
说明
pg_end_copy
([ resource $connection
] ) : bool
pg_end_copy() 在处理完 pg_put_line() 所执行的拷贝操作之后将 PostgreSQL 前端(通常为 web server 进程)与 PostgreSQL 服务器进行同步。pg_end_copy() 必须被调用,否则 PostgreSQL 服务器可能会和前端失去同步并报错。
参数
connection
- PostgreSQL database connection resource. When
connection
is not present, the default connection is used. The default connection is the last connection made by pg_connect() or pg_pconnect().
返回值
成功时返回 true
, 或者在失败时返回 false
。
