mysql_statGet current system status


string mysql_stat ([ resource $link_identifier = NULL ] )

mysql_stat() returns the current server status.



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.


Example #1 mysql_stat() example

$status explode('  'mysql_stat($link));

The above example will output something similar to:

    [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

$result mysql_query('SHOW STATUS'$link);
while (
$row mysql_fetch_assoc($result)) {
$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/
