snmp_set_valueretrieval
(PHP 4 >= 4.3.3, PHP 5)
snmp_set_valueretrieval — Specify the method how the SNMP values will be returned
说明
bool snmp_set_valueretrieval ( int $method = SNMP_VALUE_LIBRARY )
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. |
