Were you by chance polling a single host multiple time to test? Because that
seems to work. More tests below...
bugtest1.php:
<?php
// bugtest1.php - Test using built-in snmp3_get to multiple hosts
// result: fail
echo
snmp3_get('cseoc1260','[REMOVED]','authNoPriv','sha','[REMOVED]','','','SNMPv2-MIB::sysLocation.0')."\n";
echo
snmp3_get('cseoc1264','[REMOVED]','authNoPriv','sha','[REMOVED]','','','SNMPv2-MIB::sysLocation.0')."\n";
echo
snmp3_get('cseoc2260','[REMOVED]','authNoPriv','sha','[REMOVED]','','','SNMPv2-MIB::sysLocation.0')."\n";
?>
Result:
[REMOVED]:/var/www/scripts$ php bugtest1.php
STRING: EOC Building 1 (Room 1260)
PHP Warning: snmp3_get(): No response from 172.19.12.12 in

bugtest2.php:

// result: pass
echo
snmp3_get('cseoc1260','[REMOVED]','authNoPriv','sha','[REMOVED]','','','SNMPv2-MIB::sysLocation.0')."\n";
echo
snmp3_get('cseoc1260','[REMOVED]','authNoPriv','sha','[REMOVED]','','','SNMPv2-MIB::sysLocation.0')."\n";
echo
snmp3_get('cseoc1260','[REMOVED]','authNoPriv','sha','[REMOVED]','','','SNMPv2-MIB::sysLocation.0')."\n";

bugtest3.php:
<?php
// bugtest3.php - Test using NetSNMP snmpget on multiple hosts
// result: pass
echo shell_exec("snmpget -O v -v 3 -l AuthNoPriv -u [REMOVED] -a SHA -A
[REMOVED] cseoc1260 SNMPv2-MIB::sysLocation.0");
echo shell_exec("snmpget -O v -v 3 -l AuthNoPriv -u [REMOVED] -a SHA -A
[REMOVED] cseoc1264 SNMPv2-MIB::sysLocation.0");
echo shell_exec("snmpget -O v -v 3 -l AuthNoPriv -u [REMOVED] -a SHA -A

// result: pass
echo snmpget('cseoc1260','[REMOVED]','SNMPv2-MIB::sysLocation.0')."\n";

Thank you for your interest in PHP.
I can not reproduce this bug in my test environment.
Please post Net-SNMP snmpget commands with their results prooving that your 2nd
& 3rd hosts are configured to work with SNMPv3 the same way that your 1st host.

Description:
------------
Test script below returns only the first snmp3_get. The next two fail with a
PHP Warning.
This appears to be a problem in all snmp3 functions but seems to work as
expected with the snmp/snmp2 functions.
Test script:
---------------
<?php
echo
snmp3_get('device1','snmpuser','authNoPriv','sha','snmppass','','','SNMPv2-MIB::sysLocation.0')."\n";
echo
snmp3_get('device2','snmpuser','authNoPriv','sha','snmppass','','','SNMPv2-MIB::sysLocation.0')."\n";
echo
snmp3_get('device3','snmpuser','authNoPriv','sha','snmppass','','','SNMPv2-MIB::sysLocation.0')."\n";
?>
Expected result:
----------------
STRING: Location 1
STRING: Location 2
STRING: Location 3
Actual result:
--------------
STRING: Location 1
PHP Warning: snmp3_get(): No response from 192.168.0.2 in /var/www/test4.php
on line 5
PHP Warning: snmp3_get(): No response from 192.168.0.3 in /var/www/test4.php
