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
mysql_stat
(PHP 4 >= 4.3.0, PHP 5)
mysql_stat — Get current system status
Warning
This extension was deprecated in PHP 5.5.0, and it was removed in PHP 7.0.0. Instead, the MySQLi or PDO_MySQL extension should be used. See also MySQL: choosing an API guide. Alternatives to this function include:
- mysqli_stat()
-
PDO::getAttribute()
with
attributeasPDO::ATTR_SERVER_INFO
Description
mysql_stat() returns the current server status.
Parameters
-
link_identifier -
The MySQL connection. If the link identifier is not specified, the last link opened by mysql_connect() is assumed. If no such link is found, it will try to create one as if mysql_connect() had been called with no arguments. If no connection is found or established, an
E_WARNINGlevel error is generated.
Return Values
Returns a string with the status for uptime, threads, queries, open tables,
flush tables and queries per second. For a complete list of other status
variables, you have to use the SHOW STATUS SQL command.
If link_identifier is invalid, null is returned.
Examples
Example #1 mysql_stat() example
<?php
$link = mysql_connect('localhost', 'mysql_user', 'mysql_password');
$status = explode(' ', mysql_stat($link));
print_r($status);
?>The above example will output something similar to:
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
)
Example #2 Alternative mysql_stat() example
<?php
$link = mysql_connect('localhost', 'mysql_user', 'mysql_password');
$result = mysql_query('SHOW STATUS', $link);
while ($row = mysql_fetch_assoc($result)) {
echo $row['Variable_name'] . ' = ' . $row['Value'] . "\n";
}
?>The above example will output something similar to:
back_log = 50 basedir = /usr/local/ bdb_cache_size = 8388600 bdb_log_buffer_size = 32768 bdb_home = /var/db/mysql/ bdb_max_lock = 10000 bdb_logdir = bdb_shared_data = OFF bdb_tmpdir = /var/tmp/ ...

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;
}
?>
