mysql_stat (PHP 4 >= 4.3.0, PHP 5) mysql_stat -- Get current system status Descriptionstring mysql_stat ( [resource link_identifier] )
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() was called
with no arguments. If by chance no connection is found or established, an
E_WARNING level warning 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

$link = mysql_connect('localhost', 'mysql_user', 'mysql_password');
$status = explode(' ', mysql_stat($link));
print_r($status);
?> |

while ($row = mysql_fetch_assoc($result)) {
echo $row['Variable_name'] . ' = ' . $row['Value'] . "\n";
}
?> |

something similar to: back_log = 50
