SNMP::get
(PHP 5 >= 5.4.0, PHP 7, PHP 8)
SNMP::get — Fetch an SNMP object
Description
Fetch an SNMP object specified in
objectId
using GET query.
Parameters
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.
-
objectId
-
The SNMP object (OID) or objects
-
preserveKeys
-
When
objectId
is a array andpreserveKeys
set totrue
keys in results will be taken exactly as inobjectId
, otherwise SNMP::oid_output_format property is used to determinate the form of keys.
Return Values
Returns SNMP objects requested as string or array
depending on objectId
type or false
on error.
Errors/Exceptions
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.
Examples
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);
?>
The above example will output something similar to:
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();
The above example will output something similar to:
Array ( [SNMPv2-MIB::sysDescr.0] => STRING: Test server [SNMPv2-MIB::sysName.0] => STRING: myhost.nodomain )
