mysql_stat
(PHP 4 >= 4.3.0, PHP 5)
mysql_stat — 取得当前系统状态
说明
mysql_stat
([ resource
$link_identifier
] ) : stringmysql_stat() 返回当前服务器状态。
Note:
mysql_stat() 目前只返回 uptime,threads,queries,open tables,flush tables 和 queries per second。要得到其它状态变量的完整列表,只能使用 SQL 命令 SHOW STATUS。
Example #1 mysql_stat() 例子
<?php
$link = mysql_connect('localhost', "mysql_user", "mysql_password");
$status = explode(' ', mysql_stat($link));
print_r($status);
?>
以上例子将产生如下输出:
Array ( [0] => Uptime: 5380 [1] => Threads: 2 [2] => Questions: 1321299 [3] => Slow queries: 0 [4] => Opens: 26 [5] => Flush tables: 1 [6] => Open tables: 17 [7] => Queries per second avg: 245.595 )
