# pg_send_query_params

(PHP 5 >= 5.1.0RC1)

pg_send_query_params -- Submits a command and separate parameters to the server without waiting for the result(s).

## Описание

bool pg_send_query_params ( resource connection, string query, array params )

Submits a command and separate parameters to the server without waiting for the result(s).

This is equivalent to pg_send_query() except that query parameters can be specified separately from the `query` string. The function's parameters are handled identically to pg_query_params(). Like pg_query_params(), it will not work on pre-7.4 PostgreSQL connections, and it allows only one command in the query string.

## Список параметров

`connection`

  PostgreSQL database connection resource.

`query`

  The parameterised SQL statement. Must contain only a single statement. (multiple statements separated by semi-colons are not allowed.) If any parameters are used, they are referred to as $1, $2, etc.

`params`

  An array of parameter values to substitute for the $1, $2, etc. placeholders in the original prepared query string. The number of elements in the array must match the number of placeholders.

## Возвращаемые значения

Возвращает `TRUE` в случае успешного завершения или `FALSE` в случае возникновения ошибки.

Use pg_get_result() to determine the query result.

## Примеры

Пример 1. Using pg_send_query_params()

`<?php
$dbconn = pg_connect("dbname=publisher") or die("Could not connect");
// Using parameters. Note that it is not necessary to quote or escape
// the parameter.
pg_send_query_params($dbconn, 'select count(*) from authors where city = $1', array('Perth'));
// Compare against basic pg_send_query usage
$str = pg_escape_string('Perth');
pg_send_query($dbconn, "select count(*) from authors where city = '${str}'");
?>`
