SNMP::get — Fetch an SNMP object
$object_id
[, bool $preserve_keys
= false
] )
Fetch an SNMP object specified in
object_id
using GET query.
If object_id
is a string, then SNMP::get()
will return SNMP object as string. If
object_id
is a array, all requested SNMP
objects will be returned as associative array of the SNMP object ids and their
values.
object_id
The SNMP object (OID) or objects
preserve_keys
When object_id
is a array and
preserve_keys
set to TRUE
keys in results
will be taken exactly as in object_id
,
otherwise SNMP::oid_output_format property is used to determinate
the form of keys.
Returns SNMP objects requested as string or array
depending on object_id
type or FALSE
on error.
本方法默认不抛出任何异常。如果要在某些库出错时抛出 SNMPException
异常,用户需要将 SNMP 类参数 exceptions_enabled
设定为相应的值。更多细节见
SNMP::$exceptions_enabled
的解释。
Example #1 Single SNMP object
Single SNMP object may be requested in two ways: as string resulting string return value or as single-element array with associative array as output.
<?php
$session = new SNMP ( SNMP :: VERSION_1 , "127.0.0.1" , "public" );
$sysdescr = $session -> get ( "sysDescr.0" );
echo " $sysdescr \n" ;
$sysdescr = $session -> get (array( "sysDescr.0" ));
print_r ( $sysdescr );
?>
以上例程的输出类似于:
STRING: Test server Array ( [SNMPv2-MIB::sysDescr.0] => STRING: Test server )
Example #2 Miltiple SNMP objects
$session = new SNMP(SNMP::VERSION_1, "127.0.0.1", "public");
$results = $session->get(array("sysDescr.0", "sysName.0"));
print_r($results);
$session->close();
以上例程的输出类似于:
Array ( [SNMPv2-MIB::sysDescr.0] => STRING: Test server [SNMPv2-MIB::sysName.0] => STRING: myhost.nodomain )
