mysql_stat

Get current system status (PHP 4 >= 4.3.0, PHP 5, PECL mysql:1.0)
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 1462. 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 1463. 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/
