Examples

Example #1 mysqlnd_ms_dump_servers() example

{
    "myapp": {
        "master": {
            "master1": {
                "host":"master1_host",
                "port":"master1_port",
                "socket":"master1_socket",
                "db":"master1_db",
                "user":"master1_user",
                "password":"master1_pw"
            }
        },
        "slave": {
             "slave_0": {
                 "host":"slave0_host",
                 "port":"slave0_port",
                 "socket":"slave0_socket",
                 "db":"slave0_db",
                 "user":"slave0_user",
                 "password":"slave0_pw"
             },
             "slave_1": {
                 "host":"slave1_host"
             }
        }
    }
}
<?php
$link = mysqli_connect("myapp", "global_user", "global_pass", "global_db", 1234, "global_socket");
var_dump(mysqlnd_ms_dump_servers($link);
?>

The above example will output:

array(2) {
  ["masters"]=>
  array(1) {
    [0]=>
    array(5) {
      ["name_from_config"]=>
      string(7) "master1"
      ["hostname"]=>
      string(12) "master1_host"
      ["user"]=>
      string(12) "master1_user"
      ["port"]=>
      int(3306)
      ["socket"]=>
      string(14) "master1_socket"
    }
  }
  ["slaves"]=>
  array(2) {
    [0]=>
    array(5) {
      ["name_from_config"]=>
      string(7) "slave_0"
      ["hostname"]=>
      string(11) "slave0_host"
      ["user"]=>
      string(11) "slave0_user"
      ["port"]=>
      int(3306)
      ["socket"]=>
      string(13) "slave0_socket"
    }
    [1]=>
    array(5) {
      ["name_from_config"]=>
      string(7) "slave_1"
      ["hostname"]=>
      string(11) "slave1_host"
      ["user"]=>
      string(12) "gloabal_user"
      ["port"]=>
      int(1234)
      ["socket"]=>
      string(13) "global_socket"
    }
  }
}

Shouldn't it be:

var_dump(mysqlnd_ms_dump_servers($link));
