It is important to check your ports are responding before you create your own server stat script in PHP. You should aware when one of your particular service are down, such as HTTP, MySQL, POP/SMTP, etc as well you should know the current server loads, and users which will be the main indicator of a runaway script, or process.

So let’s start.

Make sure your php script ALWAYS start with

//You can replace the domain with an IP if you wish

$site = “mysite.com”; //this is the site you wish to check

// Let’s check our common ports 80, 21, and 110
$http = fsockopen($site, 80);
$ftp = fsockopen($site, 21);
$pop3 = fsockopen($site, 110);

if ($http) {
$status .= “HTTP: Working
”;
}
else {
$status .= “HTTP: Not Working
”;
}

if ($ftp) {
$status .= “FTP: Working
”;
}
else {
$status .= “FTP: Not Working
”;
}

if ($pop3) {
$status .= “POP3/SMTP: Working
”;
}
else {
$status .= “POP3/SMTP: Not Working
”;
}
echo(”$status”);

echo(”

”);

// Users and load information
$reguptime = trim(exec(”uptime”));
if ($reguptime) {
if (preg_match(”/, *(\d) (users?), .*: (.*), (.*), (.*)/”, $reguptime, $uptime)) {
$users[0] = $uptime[1];
$users[1] = $uptime[2];
$loadnow = $uptime[3];
$load15 = $uptime[4];
$load30 = $uptime[5];
}
} else {
$users[0] = “Unavailable”;
$users[1] = “–”;
$loadnow = “Unavailable”;
$load15 = “–”;
$load30 = “–”;
}

echo(”Current Users: $users[0]

Current Load: $loadnow
Load 15 mins ago: $load15
Load 15 mins ago: $load30

”);

// Operating system
$fp = @fopen(”/proc/version”, “r”);
if ($fp) {
$temp = fgets($fp);
fclose($fp);

if (preg_match(”/version (.*?) /”, $temp, $osarray)) {
$kernel = $osarray[1];
preg_match(”/[0-9]{5,} ($(.* *)$\))/”, $temp, $osarray);
$flavour = $osarray[2];
$operatingsystem = $flavour.” (”.PHP_OS.” “.$kernel.”)”;
if (preg_match(”/SMP/”, $buf)) {
$operatingsystem .= ” (SMP)”;
}
} else {
$result = “(N/A)”;
}
} else {
$result = “(N/A)”;
}

echo(”Operating System:
$operatingsystem”);
?>

It will display the status of your services, your user and load averages once you upload the above code to your server.

Now you can work with this, and make it look what ever you want, add new ports, etc.

Remember, this is just a very basic stat script.

Few Issues
You should aware that your web hosting provider will need to allow the exec() funtion, in order for this to work properly.
