Objektorientierter Stil
Prozeduraler Stil
mysqli_stat() returns a string containing information similar to that provided by the 'mysqladmin status' command. This includes uptime in seconds and the number of running threads, questions, reloads, and open tables.
Nur bei prozeduralem Aufruf: Ein von mysqli_connect() oder mysqli_init() zurückgegebenes Verbindungsobjekt.
A string describing the server status. FALSE if an error occurred.
Beispiel #1 mysqli::stat() example
Objektorientierter Stil
<?php
$mysqli = new mysqli("localhost", "my_user", "my_password", "world");
/* check connection */
if (mysqli_connect_errno()) {
printf("Connect failed: %s\n", mysqli_connect_error());
exit();
}
printf ("System status: %s\n", $mysqli->stat());
$mysqli->close();
?>
Prozeduraler Stil
<?php
$link = mysqli_connect("localhost", "my_user", "my_password", "world");
/* check connection */
if (mysqli_connect_errno()) {
printf("Connect failed: %s\n", mysqli_connect_error());
exit();
}
printf("System status: %s\n", mysqli_stat($link));
mysqli_close($link);
?>
The above examples will output:
System status: Uptime: 272 Threads: 1 Questions: 5340 Slow queries: 0 Opens: 13 Flush tables: 1 Open tables: 0 Queries per second avg: 19.632 Memory in use: 8496K Max memory used: 8560K

A small example
<?php
$dbh = new mysqli('host', 'user', 'password', 'database');
if ($dbh->connect_error) {
die("Connection Error ({$dbh->connect_errno}) {$dbh->connect_error}");
}
if (($stats = $dbh->stat()) !== FALSE) {
echo "Dumping output method stat() ...\n";
echo "$stats\n";
$statsArray = explode(" ", $stats);
print_r($stats);
}
?>
Dumping stats:
Uptime: 1095822 Threads: 5 Questions: 5326101 Slow queries: 0 Opens: 7352 Flush tables: 1 Open tables: 60 Queries per second avg: 4.860
Array
(
[0] => Uptime: 1095822
[1] => Threads: 5
[2] => Questions: 5326101
[3] => Slow queries: 0
[4] => Opens: 7352
[5] => Flush tables: 1
[6] => Open tables: 60
[7] => Queries per second avg: 4.860
)
The above code will print out a string and then attempt to create an array by exploding the string using a delimiter of two spaces (eg: " "). This should give you an array to work with, however, I'm just beginning to use this extension, so feel free to correct any errors discovered :)
