mysql_stat
Get current system status
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 and related FAQ for more information. Alternatives to this function include:

string mysql_stat(resource link_identifier= =NULL);
mysql_stat
returns the current server status.
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_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.
Example 6.53 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 6.54 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/ ...
