SYNOPSIS
Warning
This extension is deprecated as of PHP 5.5.0, and will be removed in the future. Instead, the MySQLi or PDO_MySQL extension should
be used. See also MySQL: choosing an API guide and related FAQ for more information. Alternatives to this function include:
omysqli_stat(3)
o PDO::getAttribute
string mysql_stat ([resource $link_identifier = NULL])
DESCRIPTION
mysql_stat(3) returns the current server status.
o $
link_identifier -The MySQL connection. If the link identifier is not specified, the last link opened by mysql_connect(3) is
assumed. If no such link is found, it will try to create one as if mysql_connect(3) was called with no arguments. If no connection
is found or established, an E_WARNING level error is generated.
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.

mysql_stat(3) example
<?php
$link = mysql_connect('localhost', 'mysql_user', 'mysql_password');
$status = explode(' ', mysql_stat($link));

[2] => Questions: 1321299
[3] => Slow queries: 0
[4] => Opens: 26

$result = mysql_query('SHOW STATUS', $link);
while ($row = mysql_fetch_assoc($result)) {
echo $row['Variable_name'] . ' = ' . $row['Value'] . "
";
}
?>
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/
