# snmpwalk

(PHP 3 <= 3.0.18, PHP 4 >= 4.0.0)

snmpwalk -- Fetch all the SNMP objects from an agent

## Description

``array snmpwalk` (string hostname, string community, string object_id [, int timeout [, int retries]])`

Returns an array of SNMP object values starting from the object_id() as root and `FALSE` on error.

snmpwalk() function is used to read all the values from an SNMP agent specified by the `hostname`. `Community` specifies the read community for that agent. A `NULL` `object_id` is taken as the root of the SNMP objects tree and all objects under that tree are returned as an array. If `object_id` is specified, all the SNMP objects below that `object_id` are returned.

    $a = snmpwalk("127.0.0.1", "public", "");

Above function call would return all the SNMP objects from the SNMP agent running on localhost. One can step through the values with a loop

    for ($i=0; $i < count($a); $i++) {
        echo $a[$i];
    }
