参数

method
types
SNMP_VALUE_LIBRARY The return values will be as returned by the Net-SNMP library.
SNMP_VALUE_PLAIN The return values will be the plain value without the SNMP type hint.
SNMP_VALUE_OBJECT The return values will be objects with the properties "value" and "type", where the latter is one of the SNMP_OCTET_STR, SNMP_COUNTER etc. constants. The way "value" is returned is based on which one of constants SNMP_VALUE_LIBRARY, SNMP_VALUE_PLAIN is set.

范例

Example #1 Using snmp_set_valueretrieval()

<?php
 snmp_set_valueretrieval(SNMP_VALUE_LIBRARY);
 $ret = snmpget('localhost', 'public', 'IF-MIB::ifName.1');
 // $ret = "STRING: lo"

 snmp_set_valueretrieval(SNMP_VALUE_PLAIN);
 $ret = snmpget('localhost', 'public', 'IF-MIB::ifName.1');
 // $ret = "lo";

 snmp_set_valueretrieval(SNMP_VALUE_OBJECT);
 $ret = snmpget('localhost', 'public', 'IF-MIB::ifName.1');
 // stdClass Object
 // (
 //   [type] => 4        <-- SNMP_OCTET_STR, see constants
 //   [value] => lo
 // )

 // PHP 5.4+ examples
 snmp_set_valueretrieval(SNMP_VALUE_OBJECT | SNMP_VALUE_PLAIN);
 $ret = snmpget('localhost', 'public', 'IF-MIB::ifName.1');
 // stdClass Object
 // (
 //   [type] => 4        <-- SNMP_OCTET_STR, see constants
 //   [value] => lo
 // )

 snmp_set_valueretrieval(SNMP_VALUE_OBJECT | SNMP_VALUE_LIBRARY);
 $ret = snmpget('localhost', 'public', 'IF-MIB::ifName.1');
 // stdClass Object
 // (
 //   [type] => 4        <-- SNMP_OCTET_STR, see constants
 //   [value] => STRING: lo
 // )

?>

更新日志

版本 说明
5.4.0

Constants SNMP_VALUE_PLAIN or SNMP_VALUE_LIBRARY may be combined with SNMP_VALUE_OBJECT resulting different way of representing contents of value array element in return value of GET-function. If no SNMP_VALUE_{PLAIN,LIBRARY} constant is accompanying SNMP_VALUE_OBJECT, SNMP_VALUE_LIBRARY is used.

Prior to 5.4.0 SNMP_VALUE_OBJECT effecively meant SNMP_VALUE_OBJECT|SNMP_VALUE_PLAIN.
