mysql_stat

(PHP 4 >= 4.3.0, PHP 5)

mysql_stat — Get current system status

Description

string 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 no connection is found or established, an E_WARNING level 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";
}
?>
