SNMP::get — Fetch an SNMP object
Fetch an SNMP object specified in
objectId using GET query.
If objectId is a string, then SNMP::get()
will return SNMP object as string. If
objectId is a array, all requested SNMP
objects will be returned as associative array of the SNMP object ids and their
values.
objectIdThe SNMP object (OID) or objects
preserveKeys
When objectId is a array and
preserveKeys set to true keys in results
will be taken exactly as in objectId,
otherwise SNMP::oid_output_format property is used to determinate
the form of keys.
Returns SNMP objects requested as string or array
depending on objectId type or false on error.
This method does not throw any exceptions by default.
To enable throwing an SNMPException exception when some of library errors occur
the SNMP class parameter exceptions_enabled
should be set to a corresponding value. See
SNMP::$exceptions_enabled explanation for more details.
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);
?>Il precedente esempio visualizzerà qualcosa simile a:
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();Il precedente esempio visualizzerà qualcosa simile a:
Array
(
[SNMPv2-MIB::sysDescr.0] => STRING: Test server
[SNMPv2-MIB::sysName.0] => STRING: myhost.nodomain
)
