pg_put_line

Send a NULL-terminated string to PostgreSQL backend

Description

bool pg_put_line ([ resource $connection ], string $data )

pg_put_line sends a NULL-terminated string to the PostgreSQL backend server. This is needed in conjunction with PostgreSQL's COPY FROM command.

COPY is a high-speed data loading interface supported by PostgreSQL. Data is passed in without being parsed, and in a single transaction.

An alternative to using raw pg_put_line commands is to use pg_copy_from. This is a far simpler interface.

Note:

The application must explicitly send the two characters "\." on the last line to indicate to the backend that it has finished sending its data, before issuing pg_end_copy.

Warning

Use of the pg_put_line causes most large object operations, including pg_lo_read and pg_lo_tell, to subsequently fail. You can use pg_copy_from and pg_copy_to instead.

Parameters

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.

data

A line of text to be sent directly to the PostgreSQL backend. A NULL terminator is added automatically.

Return Values

Returns TRUE on success or FALSE on failure.

Examples

Example #1 pg_put_line example

<?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);
?>
