Introduction ------------ Handlers are pieces of code that parse the raw whois output and try to add some keys to the result returned by phpWhois. In previous versions there was no standard about how these keys should be named and organized, which make them registry specific. Now all handlers have been standarized so they return a known set of keys. This is what we call 'Common Object Model'. Common Object Model ------------------- The keys that you could find in the result array returned by phpWhois are 'rawdata' , 'regyinfo' and 'regrinfo'. rawdata is always returned as it's filled by phpWhois itself. It contains the raw text output returned by the whois server. regyinfo contains information about the registry who returned that information. It has four subkeys: 'servers' which is an array with one entry for each whois server who returned the data, 'referrer' the web address of the registry, 'registar' the company name of the registry and 'type' which can be 'domain', 'ip' or 'AS'. The 'servers' array has subkeys 'server' the whois server, 'port' the whois server port and 'args' the query sent to the server. regrinfo holds the information about the domain itself. It could have the following subkeys: disclaimer ---------- Contains the disclaimer returned by the registry. registered ---------- Contains Yes or No and indicates if the domain or ip address has been found (it exists). domain ------ Only when dealing with domains. Could contain the following subkeys: name -> domain name desc -> description of the domain nserver -> array where the key is the canonical name of each nameserver and the value is the ip adresss (if none) of the server. status -> status of the domain (registry dependant) changed -> date of last change created -> creation date expires -> expire date sponsor -> registry partner where the domain was registered referer -> sponsor's URL handle -> domain handle source -> who gives this information dnssec -> domains has dnssec (boolean) network ------- Only when dealing with ip addresses. Could contain the following subkeys: name -> network/AS name inetnum -> network ip address range desc -> network description mnt-by -> who provided that network mnt-lower> who provided that network nserver -> name servers in listed order that provide inverse resolution for that net status -> status of the network (registry dependant) remarks -> remarks provided by the registry changed -> date of last change created -> creation date handle -> network/AS handle source -> who gives this information AS -- Only when dealing with Autonomus systems, could contain the same subkeys as network. owner,admin,tech,zone,billing,abuse ----------------------------------- All of these possible keys hold information about the different contacts of the domain or ip address. They all could have the same subkeys, that are: organization -> organization name name -> organization responsible type -> type of contact address -> array containing the address, the keys of that array could be just numbers, could have predefined subkeys or could be amix of numbers and predefined subkeys. Predefined subkeys are street, city, state, pcode and country phone -> phone, could also be an array of phone numers fax -> fax, same behaviour as phone email -> email, same behaviour as phone handle -> contact handle mnt-by -> who provided that contact created -> creation date changed -> last change date source -> who provided that information remarks -> remarks When information is requested on ip addresses any of those keys could be an array which will contain all data found on different whois or rwhois servers (each owner, admin, tech, etc ... found in each query). Not all handlers fill values in each of the keys defined by the Common Object Model as not all registries return the same amount of data about a domain or ip address. Also there are some differences on the format returned for some keys. Dates (created/changed/expires) are always returned in the format yyyy-mm-dd when a handler is defined for the returned data. Writing handlers ---------------- Writing handlers is easy, just look at how some of them are coded. If you write a new handler, please try to map as many as possible returned data to keys defined by the 'Common Object Model'. You can create new keys if need, but please do not do create new keys where existing predefined keys exists. Nevertheless all handlers submited will be checked before they are added to phpWhois distribution. If some tld needs special parameters or can be queried in another whois servers or web base whois servers you can setup rules in whois.servers.php so phpWhois can do the right thing. There is also a naming schema that must be followed, country handlers are named whois.XX.php, where XX is the iso country code. The handler must also define __XX_HANDLER__ and implement a class named xx_handler with a function named parse that takes two arguments: $data_str and $query. $data_str['rawdata'] contains the raw output of the query and is what need to be parsed in order to generate the Common Object Model. $query contains the domain, ip adrress or AS that it's being queried. That function must return an array with any available result in the format defined by this document. Country handlers need not to be defined in the file whois.servers.php, only when you want to use some handler for several different country domains you need to add it to the array DATA where the key is the iso country code and the value the handler name (xx). Handlers for .com/.net/.tv domains are handled by whois.gtld.php and named whois.gtld.xxx.php where xxx is the 'midname' (for example, for whois.srsplus.com, the midname is srsplus) of the whois server who provides information for that domains. If you want to reuse another handler of your handler 'midname' conflicts with any existing gtld handler you could define the handler name in the array WHOIS_GTLD_HANDLER in the file whois.servers.php. It must be implemented the same way as country handlers. Some useful utility functions have been written to aid in developing handlers. They are contained in whois.parser.php. Almost all handlers use functions provided by that file. You can see how they work by looking into the code. You also have a handler.template.php file with the squeleton of a handler. Please try to mimic the coding style of the other handlers, as this will make it easier for other people to understand and maintain. Some support functions have been developed to help you write new handlers, those functions are stored on the following files: - generic_parser_a: contains code to parse whois outputs in RPSL format, like this one.
