pg_put_line

    (PHP 4 >= 4.0.3, PHP 5, PHP 7, PHP 8)

    pg_put_line — Send a NULL-terminated string to PostgreSQL backend

    Descrição

    pg_put_line(PgSql\Connection$connection = ?, string$data): bool

    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.

    Nota:

    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().

    Aviso

    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.

    Parâmetros

    connection

    Uma instância de PgSql\Connection. Quando o parâmetro connection não for especificado, a conexão padrão será usada. A conexão padrão é a última conexão feita por pg_connect() ou pg_pconnect().

    Aviso

    A partir do PHP 8.1.0, usar a conexão padrão tornou-se defasado.

    data

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

    Valor Retornado

    Retorna true em caso de sucesso ou false em caso de falha.

    Registro de Alterações

    VersãoDescrição
    8.1.0 O parâmetro connection agora espera uma instância de PgSql\Connection; anteriormente, um resource era esperado.

    Exemplos

    Exemplo #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);
