pg_end_copy()

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

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

$connection: PostgreSQL database connection resource. When$connectionis 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。

范例

Example #1 pg_end_copy()例子

<?php 
  $conn = pg_pconnect("dbname=foo");
  pg_query($conn, "create table bar (a int4, b char(16), d float8)");
  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");
  pg_end_copy($conn);
?>
