After a more careful comparison of the command line snmpwalk and the
PHP snmpwalk it appears the items missing from the PHP snmpwalk are the
Counter64 items.

The following bash script shows that snmpwalk and snmpget/getnext
produce the same number of lines and output
when called from the command line....

#!/bin/bash
#
# Compare snmpwalk and snmpget/getnext output.
#
#set -vx
walkoid="SNMPv2-SMI::enterprises.9.9.161"
lc=$(snmpwalk -v2c -crmsy 192.168.108.254 $walkoid|wc -l)
echo snmpwalk: $lc lines.
startmib="$walkoid.1.1.1.1.2.0"
nextmib=$startmib
oper="snmpget";lc=0
while :; do
mib=$($oper -v2c -crmsy 192.168.108.254 $nextmib)
oper="snmpgetnext"
if [ $(echo $mib|grep ".9.9.161"|wc -l) -eq 0 ];then break;fi
# echo $mib
let lc=lc+1
nextmib=${mib%%\ =\ *}
done
echo snmpget/next: $lc lines.
exit

Description:
------------
Running:

PHP-5.0.3
Net-SNMP-5.2.1
Apache-(httpd-2.0.530)

PHP config Line

../configure --with-apxs2=/usr/local/apache2/bin/apxs --with-snmp

No changes to php.ini
-----------------------------------------------------------------------

Executing snmpwalk from command line (RH Linux 9) produces different
results from snmpwalk called from php.

I have a Cisco 6509 configured for Server Load Balancing.
The MIB tree for this starts at OID .1.3.6.1.4.1.9.9.161

With the following command from the Linux shell I get the folowing
results:
---------------------------------------------------------------------------
snmpwalk -v2c -crmsy 192.168.108.254 .1.3.6.1.4.1.9.9.161

Most of the indexed items are missing from the output. I believe this
is because
the php snmpwalk function does not actually call snmpwalk. It uses a
combination
of snmpget and snmpgetnext calls which do not visit every branch in the
MIB tree.

Because the indexes are part of the OID field the output of snmpget and
snmpgetnext
calls are missing vital information.

I would suggest the php snmpwalk function be coded to call the actual
snmpwalk routine.
There would then be no need for the snmprealwalk and snmpwalkoid
functions.

Reproduce code:
---------------
command line call:
---------------------------------------------------------
snmpwalk -v2c -crmsy 192.168.108.254 .1.3.6.1.4.1.9.9.161


php script:
---------------------------------------------------------
<html><head><title> SLB info</title></head><body>
<?php
$a = snmpwalk("192.168.108.254", "rmsy", ".1.3.6.1.4.1.9.9.161");
for ($i=0; $i < count($a); $i++) {echo " {$a[$i]}<br />";}
?>
</body></html>
