0.2 (2009-11-30)

  • added callbacks
  • added btest


  • initial release


The main purpose of another RouterOS PHP API class it to simplify configuration update processes. Example: We have about 20 access points and for each of them we have connected about 20 wds links. Using automatic configuration process we can store information about all wds links in one place. It can be MySQL database.

Using set of configuration files router's can be divided into function groups (ie. router, main-access-point, client-access-point, switch) and be configured from central server automatically. ONLY changed configuration will be updated, so in most cases no configuration will change.


Requires a very good knowledge of RouterOS configuration tree, PHP Runtime and API access to RouterOS.

RouterOS class


Base class for handing RouterOS API interface. It implements methods of getting and setting values as well restarting router.


All commands accepts two forms of arguments. Either using string or using array. Prefered way is to use array.


From version 0.2 interface supports many simulatenous commands using user callbacks. Every function with $callback parameter support asynchronous operation. If valid $callback would be passed function returns instead of results assigned ".tag" value to callback or FALSE on failure.

Callback Function

function myCallbackFunction($conn, $state, $results);

  • conn - RouterOS object
  • state - indicate callback boolean state. TRUE the response is either "!done" or "!re". FALSE the response is "!trap"
  • results - contains additional arguments for response. If NULL callback got "!done" status otherwise contains associative array of results from API server.

To specify command (in RouterOS configuration tree) use:

  • slash delimeted string:
  • array of string:
    array("ip", "firewall", "string")

To specify configuration line (for command) use:

  • space delimeted string:
    chain=forward action=drop in-interface=ether1
  • associative array of string:
    array("chain"=>"forward", "action"=>"drop", "in-interface"=>"ether1")

Class Variables

  • public $readOnly = FALSE;

    Read-only flag. If set to TRUE: RouterOS class will not change nor remove any item.

Class Methods

  • static function connect($host, $login, $password, $port = 8728, $timeout = 5)

    Connects to new RouterOS using specified "host" with specified "login" and "password" on "port".

    $conn = RouterOS::connect("", "admin", "adminpassword");
  • public function setTimeout($timeout = 5)

    Set socket timeout in seconds.

  • function dispatch(&$continue)

    Dispatches comming messages from server to functions executed as callbacks. Returns TRUE if there is one or more pending functions.

    continue - flag to manually break listener loop (it can be done from callback). Initial value should be set to TRUE.

    $continue = TRUE; $conn->dispatch($continue);
  • function getall($cmd, $proplist = FALSE, $args = array(), $assoc = FALSE, $callback = FALSE)

    Get all values for specified command. Returns array of results.

    cmd - name of command (string or array)

    proplist - list of values to get (string comma delimeted or array)

    args - additional arguments, ie. queries (string space delimeted or associative array)

    assoc - name of associative key

RouterOSParser class


Parser class to load configuration from file and perform differencing configuration update.

Parser output should be shown in text/plain content-type!

Order of sections defines order of configuration updates.

How it works

  • For each section: getall items from RouterOS
  • ignore all dynamic entries, remove all invalid entries
  • try to classify RouterOS item to either ignore or to pass list
  • try to match RouterOS item with local item using defined keys, if no match found remove, if match found update only what changed
  • reorder RouterOS item list
  • add not found items to RouterOS



One line is one command. Command can be either: comment, flow function, include function, user function definer or configurer function. Each line is firstly trimmed from whitespaces.


Comment can only by started from new line and after # char. Before # can be zero or more whitespaces. Comment can't be added after command!

# Sample comment


To use variable add % before and after variable name: To get value of my-variable:


To define variable in script use var keyword

var [variable-name] [variable-value]
var my-variable test-variable
var my-variable test-variable-using-previous-value-of-my-variable-%my-variable%

Flow functions

In script files there are a few flow functions: if, elseif, else, endif. Flow functions can be nested. One flow block if-else-endif has to be located in ONE file. So simply You can't start flow block in one file and end it in another.

if [left-value] [operator] [right-value]
# [commands execute when first comparision is true] ...
elseif [left-value] [operator] [right-value]
# [commands execute when second comparision is true] ...
# [commands execute when neither first nor second comparision is true] ...

left-value, right-value - either string or variable

if %version% ~= 4.*
# execute commands for version 4.*
# execute commands for all other versions 4.*


  • = - left is equal right
  • != - left is not equal tight
  • < - left is less than right
  • <= - left is less or equal right
  • > - left is greater than right
  • >= - left is greater or equal right
  • ~= - right is wildcardly equal left (using fnmatch from php)
  • !~= - right is wildcardly not equal left (using fnmatch from php)

Including files

Script file can include another file and parse it in place. Current file path is used to include file. Each file can be included more than once.

include [file-name]

Includes file if exists. If file doesn't exist parser will continue.

require [file-name]

Require file. If file doesn't exist parser will return with error.

Other commands

  • set [alias] [key=value] [key2=value2]...
    add [alias] [key=value] [key2=value2]...

    Set or add (synonims) config line.

  • function [cmd-name] [$arg1] [$arg2=$default2]...
    # function body

    Add new user php function. Always in defined function first argument is $parser to access current parser context.

    function my_first_function $srcaddress $dstaddress=""
    # do some crazy stuff with $parser.
  • ignore [alias] [key=value] [key2=value2]...
    pass [alias] [key=value] [key2=value2]...

    Add ignore or pass config line. See RouterOSParser::ignore or RouterOSParser::pass functions.

  • flush [alias] [alias2]...

    Clean all configuration for specified alias!

  • section [alias] [cmd] [type] [keys or false] [default_key=default_value]...

    Add new section alias of type to configuration update with comma delimeted group keys and list of default_key. See RouterOSParser::section function.

    section firewall-filter /ip/firewall/filter addset_order
    section wireless-wds /interface/wireless/wds addset name disabled=no
  • disable [alias] [alias2]...

    Remove section from configuration update.

    disable firewall-filter queue-tree
  • [cmd-name] [arg1] [arg2]...

    Execute user defined function with args.


Section Types

To perform automatic update updater has to know what type of data to expect. Proper section type has to be specified.

  • addset - add, set or remove items (where .id is specified for an item) in unspecified order (ie. /queue/tree, /queue/types...)
  • addset_order - add, set or remove items where order of items matters(ie. /ip/firewall/filter, /queue/simple, /ip/dns/static...)
  • set - only set items (where .id is specified for an item), don't remove or add an new one (ie. /interface, /queue/interface...)
  • value - only set variables (where are values not items) (ie. /ip/firewall/connection/tracking, /ip/dns)

Class Variables

  • public $logs = array();

    Array of logs from section update.

  • public $showIgnored = FALSE;

    Whatever to show in logs items which found to be "ignore" or "pass".

  • public $currentContext;

    Information about current processed line (can be accessed from user php functions).

Class Methods

  • function error($message)

    DIE execution with specified error message.

  • function define($key, $value = FALSE)

    Define or undefine script variable: %key%

  • function variable($key)

    Get value of script variable: %key%
