Here's a fresh list of API for SNMPv1, SNMPv2c, and SNMPv3 as of PHP 5.2.4:



SNMPv1

------

string snmpget(string host, string community, string object_id [, int timeout [, int retries]]);



string snmpgetnext(string host, string community, string object_id [, int timeout [, int retries]]);



array snmpwalk(string host, string community, string object_id [, int timeout [, int retries]]);



array snmprealwalk(string host, string community, string object_id [, int timeout [, int retries]]);



bool snmp_get_quick_print(void);



void snmp_set_quick_print(int quick_print);



void snmp_set_enum_print(int enum_print);



void snmp_set_oid_output_format(int oid_format);



int snmpset(string host, string community, string object_id, string type, mixed value [, int timeout [, int retries]]);



SNMPv2c

-------

string snmp2_get(string host, string community, string object_id [, int timeout [, int retries]]);



string snmp2_getnext(string host, string community, string object_id [, int timeout [, int retries]]);



array snmp2_walk(string host, string community, string object_id [, int timeout [, int retries]]);



array snmp2_real_walk(string host, string community, string object_id [, int timeout [, int retries]]);



int snmp2_set(string host, string community, string object_id, string type, mixed value [, int timeout [, int retries]]);



SNMPv3

------

int snmp3_get(string host, string sec_name, string sec_level, string auth_protocol, string auth_passphrase, string priv_protocol, string priv_passphrase, string object_id [, int timeout [, int retries]]);



int snmp3_getnext(string host, string sec_name, string sec_level, string auth_protocol, string auth_passphrase, string priv_protocol, string priv_passphrase, string object_id [, int timeout [, int retries]]);



int snmp3_walk(string host, string sec_name, string sec_level, string auth_protocol, string auth_passphrase, string priv_protocol, string priv_passphrase, string object_id [, int timeout [, int retries]]);



int snmp3_real_walk(string host, string sec_name, string sec_level, string auth_protocol, string auth_passphrase, string priv_protocol, string priv_passphrase, string object_id [, int timeout [, int retries]]);



int snmp3_set(string host, string sec_name, string sec_level, string auth_protocol, string auth_passphrase, string priv_protocol, string priv_passphrase, string object_id, string type, mixed value [, int timeout [, int retries]]);



General

-------

int snmp_set_valueretrieval(int method);



int snmp_get_valueretrieval();



int snmp_read_mib(string filename);



SNMPv3 options

--------------

SNMPv3 offers a different authentication/authorization scheme than previous versions of SNMP.  To aid in using the API listed above, here is a brief explanation of each of the unique parameters used in the snmp3_* functions.



$sec_name - the "username" used for authentication to the system



$sec_level - the authentication scheme ('noAuthNoPriv', 'authNoPriv', or 'authPriv')



$auth_protocol - the encryption protocol used for authentication ('MD5' [default] or 'SHA')



$auth_passphrase - the encrypted key to use as the authentication challenge



$priv_protocol - the encryption protocol used for protecting the protocol data unit ('DES' [default], 'AES128', 'AES192', or 'AES256')



$priv_passphrase - the key to use for encrypting the protocol data unit



There are good code snippets available on http://forums.cacti.net/about5403.html for more information.

For my purposes in PHP coding, I have the following SNMP options set, always.  These aren't documented very well in PHP's docs, but they make dealing with the SNMP results a LOT easier:



<?php

// Return back the numeric OIDs, instead of text strings.

snmp_set_oid_numeric_print(1);



// Get just the values.

snmp_set_quick_print(TRUE);



// For sequence types, return just the numbers, not the string and numbers.

snmp_set_enum_print(TRUE); 



// Don't let the SNMP library get cute with value interpretation.  This makes 

// MAC addresses return the 6 binary bytes, timeticks to return just the integer

// value, and some other things.

snmp_set_valueretrieval(SNMP_VALUE_PLAIN);  

?>
