PHP 5.6.0RC3 is available

mysql_stat

(PHP 4 >= 4.3.0, PHP 5)

mysql_statGet 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 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 #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');
$result mysql_query('SHOW STATUS'$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/
...

The following script can be used to clearly print out the results of mysql_stat().

<?php
    mysql_connect
("localhost", "username", "password");
   
$array = explode("  ", mysql_stat());
    foreach (
$array as $value){
        echo
$value . "<br />";
    }
?>

Outputs something similar to:

Uptime: 698
Threads: 1
Questions: 4
Slow queries: 0
Opens: 19
Flush tables: 1
Open tables: 12
Queries per second avg: 0.5

if you need the complete status as outputted by the "show status" command. Try this function.
<?
function mysql_status($db=NULL) {
if(!mysql_ping($db))
$db=mysql_connect("localhost","user","password");
$res=mysql_query("show status",$db);
while (list($key,$value)=mysql_fetch_array($res))
$sql[$key]=$value;
return $sql;
}
?>
