Please try using this snapshot:
http://snaps.php.net/php-trunk-latest.tar.gz
For Windows:
http://windows.php.net/snapshots/
Please check OO API from trunk. It has an option to specify session-wise OID output format and more.
Sources in trunk can be compiled against downto php 5.2

The snmp module needs a bit of rededesign. It should handle many of the commands from the native
calls, like multiple OID get's in a single array, in other words, make the OID a mixed type for
a get request.
Also, the snmp functions should require a resource (aka snmp session) in order to work, just like is
done in the API, for which it would be based.
In that case, to setup a quick print, you start a session, receive a pointer to a
(structure/resource) in return and then all subsequent calls need to also pass the resource to the
function. Once you are done, you need to close the sessions.
This will have to be a new class of calls though as simply changing thing around will make life
difficult for everyone.

It's pretty simple issue, propably need to add some netsnmp shutdown function in RINIT which
clears all the settings between requests.

Description:
------------
When PHP runs under Apache and snmp_set_quick_print(TRUE) is issued, the behavior of all
SNMP-related functions will be "quick print" for the lifetime of the PID.
NET-SNMP Support => enabled
NET-SNMP Version => 5.4.1
PHP version: 5.2.4
There are two possibilities:
1) This behavior is "by design": If this is the case I think the manual page for
snmp_set_quick_print() needs a warning for this behavior.
2) This is a bug: For each PID the behavior should be (re)set to the default behavior after
execution of the script.
Reproduce code:
---------------
pet@workmate:/tmp$ sudo /etc/init.d/apache2 restart > /dev/null 2>&1
pet@workmate:/tmp$ for (( i=0; i<5; i++ )) ; do links -dump http://localhost/snmp_get_quick_print.php;
done
snmp_get_quick_print: '' | pid: '9402'
snmp_get_quick_print: '' | pid: '9403'
snmp_get_quick_print: '' | pid: '9404'
snmp_get_quick_print: '' | pid: '9405'
snmp_get_quick_print: '' | pid: '9406'
pet@workmate:/tmp$ links -dump http://localhost/snmp_set_quick_print.php
snmp_set_quick_print: '' | pid: '9406'
pet@workmate:/tmp$ for (( i=0; i<5; i++ )) ; do links -dump http://localhost/snmp_get_quick_print.php;
done
snmp_get_quick_print: '' | pid: '9403'
snmp_get_quick_print: '' | pid: '9404'
snmp_get_quick_print: '' | pid: '9446'
snmp_get_quick_print: '' | pid: '9405'
snmp_get_quick_print: '1' | pid: '9406'
