pg_put_line
(PHP 4 >= 4.0.3, PHP 5)
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 useful for example for very high-speed inserting of data into a table, initiated by starting a PostgreSQL copy-operation. That final NULL-character is added automatically. Возвращает TRUE в случае успешного завершения, FALSE в случае возникновения ошибки.
Замечание: The application must explicitly send the two characters "\." on the last line to indicate to the backend that it has finished sending its data.
Пример 1. High-speed insertion of data into a table
<?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);
