pg_end_copy

(PHP 4 >= 4.0.3, PHP 5, PHP 7, PHP 8)

pg_end_copy — 与 PostgreSQL 后端同步

说明

pg_end_copy(?PgSql\Connection $connection = null): 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

An PgSql\Connection instance. When connection is null, the default connection is used. The default connection is the last connection made by pg_connect() or pg_pconnect().

警告

As of PHP 8.1.0, using the default connection is deprecated.

返回值

成功时返回 true，或者在失败时返回 false。

更新日志

版本	说明
8.1.0	现在 `connection` 参数接受 PgSql\Connection 实例，之前接受 resource。
8.0.0	`connection` 现在可以为 null。

示例

  pg_put_line($conn, "3\thello world\t4.5\n");
