SNMP::get — Fetch an SNMP object
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_idThe 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 Multiple 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
)
