mysql_stat

说明

string mysql_stat ( [resource link_identifier] )

mysql_stat() 返回当前服务器状态。

注: 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。

例子 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 )

if you need the complete status as outputted by the "show status" command. Try this function.

<?

function mysql_status($db=NULL) {

if(!mysql_ping($db))

$db=mysql_connect("localhost","user","password");

$res=mysql_query("show status",$db);

while (list($key,$value)=mysql_fetch_array($res))

$sql[$key]=$value;

return $sql;

}

?>
