pg_put_line — Send a NULL-terminated string to PostgreSQL backend
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().
A line of text to be sent directly to the PostgreSQL backend. A NULL terminator is added automatically.
TRUE en caso de éxito o
FALSE en caso de error.
Ejemplo #1 pg_put_line() example
$conn = pg_pconnect("dbname=foo");
pg_query($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");
