# snmp_read_mib

(PHP 5, PHP 7)

snmp_read_mib — Reads and parses a MIB file into the active MIB tree

### Description

snmp_read_mib ( string `$filename` ) : bool

This function is used to load additional, e.g. vendor specific, MIBs so that human readable OIDs like VENDOR-MIB::foo.1 instead of error prone numeric OIDs can be used.

The order in which the MIBs are loaded does matter as the underlying Net-SNMP libary will print warnings if referenced objects cannot be resolved.

### Parameters

`filename`

  The filename of the MIB.

### Examples

Example #1 Using snmp_read_mib()

`<?php
print_r( snmprealwalk('localhost', 'public', '.1.3.6.1.2.1.2.3.4.5') );
snmp_read_mib('./FOO-BAR-MIB.txt');
print_r( snmprealwalk('localhost', 'public', 'FOO-BAR-MIB::someTable' );
?>`

The above example is made up but the results would look like:

    Array
    (
        [iso.3.6.1.2.1.2.3.4.5.0] => Gauge32: 6
    )
    Array
    (
        [FOO-BAR-MIB::someTable.0] => Gauge32: 6
    )
