mysql_stat

(PHP 4 >= 4.3.0, PHP 5, PECL mysql:1.0)

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/ ...
