pg_put_line

Send a NULL-terminated string to PostgreSQL backend (PHP 4 >= 4.0.3, PHP 5)
bool pg_put_line ( string data )

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 1963. pg_put_line() example

copy to clipboard

<?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);
?>
