pg_put_line

说明

bool pg_put_line ( [resource connection, string data] )

pg_put_line() 向 PostgreSQL 后端服务器发送以 NULL 结尾的字符串。例如可以通过 PostgreSQL 的 copy 操作来向表中高速插入数据。结尾的 NULL 字符会自动加入。如果成功则返回 TRUE，失败则返回 FALSE。

注: 应用程序必须明确地在最后一行发送两个字符 "\." 来向后端指明发送数据结束。

例子 1. 向表中高速插入数据
<?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); ?>

This is the function you need if you are running into the infamous "must be superuser to COPY to or from a file" error from postgres.
