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

### Descripción

pg_send_query_params(PgSql\Connection `$connection`, string `$query`, array `$params`): int|bool

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.

### Parámetros

`connection`

  An PgSql\Connection instance.

`query`

  The parameterized 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.

### Valores devueltos

Returns `true` on success, `false` or `0` on failure. Use pg_get_result() to determine the query result.

### Historial de cambios

8.1.0 | The `connection` parameter expects an PgSql\Connection instance now; previously, a recurso was expected.

### Ejemplos

Ejemplo #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}'");
?>`
