pg_get_pid

Gets the backend's process ID

Description

int pg_get_pid(PgSql\Connection $connection)

pg_get_pid gets the backend's (database server process) PID. The PID is useful to determine whether or not a NOTIFY message received via pg_get_notify is sent from another process or not.

Parameters

connection

An PgSql\Connection instance.

Return Values

The backend database process ID.

Changelog

Version Description
8.1.0 The connection parameter expects an PgSql\Connection instance now; previously, a resource was expected.

Examples

Example #1 PostgreSQL backend PID

<?php 
$conn = pg_pconnect("dbname=publisher");
if (!$conn) {
  echo "An error occurred.\n";
  exit;
}

// Backend process PID. Use PID with pg_get_notify()
$pid = pg_get_pid($conn);
?>
