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 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
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 VARIABLES', $link);
while ($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/ ... |
