Returns an associative array with object ids and their
respective object value starting from the object_id as root and FALSE on error.
snmpwalkoid() function is used
to read all object ids and their respective values from an
SNMP agent specified by the
hostname. Community specifies the read community for that agent. A NULL
object_id is taken as 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.
The existence of snmpwalkoid()
and
snmpwalk() has historical reasons. Both functions are
provided for backward compatibility.
Above function call would return all the SNMP objects
from the SNMP agent running on localhost. One can step
through the values with a loop
