PHP使用SNMP相关函数的问题
SNMP服务已经配置好了

使用PHP_SNMP.DLL模块

使用函数 SNMPWALK

原代码如下
$a = snmpwalkoid("127.0.0.1", "public", "");
?>


for (reset($a); $i = key($a); next($a)) {
  echo "$i: $a[$i]
\n";
}
?>
这个是没问题的 但是一旦指定相关OBJECT就会出问题 SNMPWALK帮助文档提供的原代码中

$host = '127.0.0.1';
$community = 'public';
$object_id = 'IF-MIB::interfaces.ifTables.ifEntry.ifAdminStatus';

$sysdesc = snmpwalk($host, $community, $object_id);
print_r($sysdesc);
?>

提示SNMPWALK出错 
但是是有东西输出的

错误信息 Warning: snmpwalk() [function.snmpwalk]: Invalid object identifier: IF-MIB::interfaces.ifTables.ifEntry.ifAdminStatus in E:\work\php\black\snmpwalk3.php on line 6

输出信息
Array ( [0] => "Windows WWW-476F9BE6F90 5.1.2600 Service Pack 3 XP Professional x86 Family 6 Model 23 Stepping 10" [1] => OID: enterprises.8072.3.2.13 [2] => Timeticks: (138255) 0:23:02.55 [3] => "Me " [4] => "WWW-476F9BE6F90" [5] => "Right here, right now."

求帮助

------解决方案--------------------
'IF-MIB::interfaces.ifTables.ifEntry.ifAdminStatus'
当初我也碰到这个问题了。
网上找到的都是这种表达方式,好像是linux系统专用的。
windows系统下,需要用.iso.开头的地址,或者0.1.3.6数字形式的。
iso就是1.

Invalid object identifier就是表示这个'IF-MIB::interfaces.ifTables.ifEntry.ifAdminStatus'不存在。

Dependency Injection in PHP: Code Examples for BeginnersDependency Injection in PHP: Code Examples for BeginnersMay 14, 2025 am 12:08 AM

You should care about DependencyInjection(DI) because it makes your code clearer and easier to maintain. 1) DI makes it more modular by decoupling classes, 2) improves the convenience of testing and code flexibility, 3) Use DI containers to manage complex dependencies, but pay attention to performance impact and circular dependencies, 4) The best practice is to rely on abstract interfaces to achieve loose coupling.

Dependency Injection vs. Service Locator in PHPDependency Injection vs. Service Locator in PHPMay 13, 2025 am 12:10 AM

Select DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.
