pg_host()

(PHP 4, PHP 5, PHP 7)

返回和某连接关联的主机名

说明

pg_host(resource $connection): string

pg_host()返回指定的 PostgreSQL$connection资源号所连接到的主机名称。

参见pg_connect()和pg_pconnect()。

This is a simple example of this function, which returns the name of which PostreSQL Database you are currently connected to.
<?php
  $pgsql_conn = pg_connect("dbname=mark host=localhost");
  if ($pgsql_conn) {
    print "Successfully connected to: " . pg_host($pgsql_conn) . "<br/>\n";
  } else {
    print pg_last_error($pgsql_conn);
    exit;
  }
?>
This function is extremely useful for sites which connect to multiple Postgresql services.
