mysql_stat — 取得当前系统状态
<h3>说明</h3>
string <strong>mysql_stat</strong>
([ resource <code>$link_identifier</code>
] )
<p>
<strong>mysql_stat()</strong> 返回当前服务器状态。
</p>
<p><strong>Note</strong>:
<p>
<strong>mysql_stat()</strong>

<?php
$link = mysql_connect('localhost', "mysql_user", "mysql_password");
$status = explode(' ', mysql_stat($link));
print_r($status);
