mysqlnd_ms_dump_servers — Returns a list of currently configured servers

설명

array mysqlnd_ms_dump_servers ( mixed $connection )

Returns a list of currently configured servers.

인수

connection: A MySQL connection handle obtained from any of the connect functions of the mysqli, mysql or PDO_MYSQL extensions.

반환값

FALSE on error. Otherwise, returns an array with two entries masters and slaves each of which contains an array listing all corresponding servers.

The function can be used to check and debug the list of servers currently used by the plugin. It is mostly useful when the list of servers changes at runtime, for example, when using MySQL Fabric.

        "slave": {
             "slave_0": {
                 "host":"slave0_host",
                 "port":"slave0_port",

<?php
$link = mysqli_connect("myapp", "global_user", "global_pass", "global_db", 1234, "global_socket");
var_dump(mysqlnd_ms_dump_servers($link);
?>

위 예제의 출력:

array(2) {
  ["masters"]=>
  array(1) {
    [0]=>
    array(5) {
      ["name_from_config"]=>
      string(7) "master1"

Shouldn't it be:

var_dump(mysqlnd_ms_dump_servers($link));
?
