Basically this is because of loosy algorithm predicting string length produced by snmp library function that prints OID values.
As a walkaround one can set
===
snmp_set_valueretrieval(SNMP_VALUE_PLAIN);
===
(or OO API [SNMP Object]->valueretrieval)
and then use bin2hex to decode binary string into hex string.

do this on a CISCO 2950, 2960, 3750 or 4500 (that's all devices i have tested) with proper community and ip.

<?php echo snmpget("192.168.1.1","2c","public","1.3.6.1.4.1.9.9.46.1.6.1.1.4"); ?>
