Descrizione

string mysql_stat ([ resource $identificativo_connessione ] )

mysql_stat() restituisce l'attuale stato del server.

Nota:

mysql_stat() attualmente restituisce solo le seguenti informazioni: uptime, thread, query, tabelle aperte, tabelle svuotate e query al secondo. Per una lista completa delle altre variabili di stato si usi il comando SQL SHOW STATUS.

Example #1 mysql_stat() example

<?php
$connessione 
mysql_connect('localhost'"utente_mysql""password_mysql");
$stato explode('  'mysql_stat($connessione));
print_r($stato);
?>

L'esempio riportato sopra dovrebbe produrre il seguente output:

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
)

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;
}
?>
