Opis

mysql_stat ([ resource $identyfikator_połączenia ] ) : string

mysql_stat() zwraca aktualny stan serwera.

Informacja:

mysql_stat() w chwili obecnej zwraca jedynie czas pracy serwera, liczbę wątków, zapytań, otwartych tabel, oraz liczbę zapytań na sekundę. Pełną listę parametrów opisujących stan można uzyskać wydając komendę SQL: SHOW STATUS.

mysql_connect('localhost''uzytkownik''haslo');
printf("%s\n"mysql_stat($link));
?>

Powyższy przykład da następujący wynik:

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;
}
?>
