范例
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);
?>
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"]=> 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" } } }
