Using function Snmpwalk

The original code is as follows
$a = snmpwalkoid ("127.0.0.1", "Public", "" ");
?>


for (reset ($a); $i = key ($a); next ($a)) {
echo "$i: $a [$i]
\ n ";
}
?>
This is fine, but once you specify the relevant object, it will be a problem snmpwalk the original code provided in the Help documentation

$host = ' 127.0.0.1 ';
$community = ' public ';
$object _id = ' if-mib::interfaces.iftables.ifentry.ifadminstatus ';

$sysdesc = Snmpwalk ($host, $community, $object _id);
Print_r ($SYSDESC);
?>

Prompt Snmpwalk Error
But there's something out there.

' If-mib::interfaces.iftables.ifentry.ifadminstatus '
I had this problem at the beginning.
These expressions are found on the web, as if they were dedicated to Linux.
Under Windows systems, you need an address that begins with an. iso., or 0.1.3.6 in digital form.
ISO is 1.

Invalid object identifier means that the ' if-mib::interfaces.iftables.ifentry.ifadminstatus ' does not exist.
