$hostname,$security_name,$security_level,$auth_protocol,$auth_passphrase,$privacy_protocol,$privacy_passphrase,$object_id,$timeout = -1,$retries = -1
snmp3_walk() function is used to read all the values from
an SNMP agent specified by the hostname.
The authentication and privacy arguments must always be passed, but their
values are ignored when security_level does not use
them.
hostnameThe hostname of the SNMP agent (server).
security_nameThe security name, usually some kind of username.
security_levelThe security level: "noAuthNoPriv",
"authNoPriv", or "authPriv".
auth_protocolThe authentication protocol: "MD5", "SHA",
"SHA256", or "SHA512".
auth_passphraseThe authentication passphrase.
privacy_protocolThe privacy protocol: "DES", or "AES",
also accepted as "AES128". "AES192", "AES192C",
"AES256", and "AES256C" are accepted when supported by the
Net-SNMP library.
privacy_passphraseThe privacy passphrase.
object_id
If an empty string, object_id is taken as
.1.3.6.1.2.1, the root of the SNMP
objects tree, and all objects under that tree are returned as an array.
If object_id is specified, all the SNMP objects
below that object_id are returned.
timeoutThe number of microseconds until the first timeout.
retriesThe number of times to retry if timeouts occur.
Returns an array of SNMP object values starting from the
object_id as root or false on error.

示例 #1 snmp3_walk() Example
<?php
$ret = snmp3_walk('localhost', 'james', 'authPriv', 'SHA', 'secret007', 'AES', 'secret007', 'IF-MIB::ifName');
var_export($ret);
?>Above function call would return all the SNMP objects from the SNMP agent running on localhost:
array ( 0 => 'STRING: lo', 1 => 'STRING: eth0', 2 => 'STRING: eth2', 3 => 'STRING: sit0', 4 => 'STRING: sixxs', )
