The following script can be used to clearly print out the results of mysql_stat().
<?php
mysql_connect("localhost", "username", "password");
$array = explode(" ", mysql_stat());
foreach ($array as $value){
echo $value . "<br />";
}
?>
Outputs something similar to:
Uptime: 698
Threads: 1
Questions: 4
Slow queries: 0
Opens: 19
Flush tables: 1
Open tables: 12
Queries per second avg: 0.5

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;
}
?>
