mysql_stat


Description

string mysql_stat(resource link_identifier= =NULL);

mysql_stat returns the current server status.

Parameters

link_identifier

The MariaDB 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.

Examples

Example 20.66. 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 20.67. 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/
