snmpwalkoid — Query for a tree of information about a network entity
snmpwalkoid() function is used to read all object ids and their respective values from an SNMP agent specified by hostname .
The existence of snmpwalkoid() and snmpwalk() has historical reasons. Both functions are provided for backward compatibility. Use snmprealwalk() instead.
The SNMP agent.
The read community.
If 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.
Returns an associative array with object ids and their respective object value starting from the object_id as root or FALSE on error.
Example #1 snmpwalkoid() Example
<?php
$a = snmpwalkoid("127.0.0.1", "public", "");
for (reset($a); $i = key($a); next($a)) {
echo "$i: $a[$i]<br />\n";
}
?>
