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.
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().
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
NULLterminator is added automatically.
Examples
Example 1963. 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);
?>
