of SNMP objects starting from object_id
and return not only their values but also their object ids.
host
The hostname of the SNMP agent (server).
community
The read community.
object_id
The SNMP object id which precedes the wanted one.
timeout
The number of microseconds until the first timeout.
retries
The number of times to retry if timeouts occur.

Example #1 Using snmprealwalk()
<?php
print_r(snmprealwalk("localhost", "public", "IF-MIB::ifName"));
?>
The above will output something like:
Array

[IF-MIB::ifName.1] => STRING: lo
[IF-MIB::ifName.2] => STRING: eth0
[IF-MIB::ifName.3] => STRING: eth2
[IF-MIB::ifName.4] => STRING: sit0
[IF-MIB::ifName.5] => STRING: sixxs
)
