mysqlnd_ms_dump_servers — Returns a list of currently configured servers
Returns a list of currently configured servers.
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.

{
"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",

},
"slave_1": {

}
<?php
$link = mysqli_connect("myapp", "global_user", "global_pass", "global_db", 1234, "global_socket");
var_dump(mysqlnd_ms_dump_servers($link);
?>
以上例程会输出：
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"]=>

Shouldn't it be:
var_dump(mysqlnd_ms_dump_servers($link));
