PHP 8.1.28 Released!

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

示例 #1 pg_end_copy() 示例

$conn
= pg_pconnect("dbname=foo");

pg_query($conn, "copy bar from stdin");
pg_put_line($conn, "3\thello world\t4.5\n");
pg_put_line($conn, "4\tgoodbye world\t7.11\n");
pg_put_line($conn, "\.\n");
