1. About Domain Class
=====================
This class provides informations about internet domains and
their registrars. It can give you the WHOIS informations or
tells if a domain is available for registration or not.
Some more functions gives back further informations about
the domain.
2. Function reference
=====================
2.1 domain() :: constructor
===========================
Use this function to initialize the class with your domain.
include("domain.class.php");
$my_domain=new domain("the-domain-to-check.com");
2.2 info() :: whois information
===============================
The info() function returns the pure whois information from
the correct whois server without striping any information.
include("domain.class.php");
// Initializing domain class
$my_domain=new domain("the-domain-to-check.com");
// printing out whois information
echo $my_domain->info();
2.3 html_info() :: whois information - html formated
====================================================
Identical to the info() function, but code will be returned
as html code with
for new lines.
include("domain.class.php");
// Initializing domain class
$my_domain=new domain("the-domain-to-check.com");
// printing out whois information
echo $my_domain->html_info();
2.4 is_available() :: the availability of a domain
==================================================
Checks if a domain is available for registration or not.
include("domain.class.php");
// Initializing domain class
$my_domain=new domain("the-domain-to-check.com");
// Checking availability
if($my_domain->is_available()==true){
echo "Domain is not registered yet";
}else{
echo "Domain is already registered";
}
2.5 get_whois_server() :: the whois server of the domain
========================================================
Returns the whois server of the set domain.
include("domain.class.php");
// Initializing domain class
$my_domain=new domain("the-domain-to-check.com");
// Return the actual whois server of the domain
echo $my_domain->get_whois_server();
2.6 get_tld() :: the tld of the domain
======================================
This function returns the "suffix" of the domain.
For example the domain "my-domain.cc" will return "cc".
include("domain.class.php");
// Initializing domain class
$my_domain=new domain("the-domain-to-check.com");
// Returning the tld of the domain
echo $my_domain->get_tld(); // Will return "com"
2.7 get_domain :: the domain name without tld
=============================================
Returns the domain name without tld.
include("domain.class.php");
// Initializing domain class
$my_domain=new domain("the-domain-to-check.com");
// Returning the domain without tld
echo $my_domain->get_domain(); // Will return "the-domain-to-check"
2.8 get_fulldomain() :: the domain name
=======================================
Returns the full domain name.
include("domain.class.php");
// Initializing domain class
$my_domain=new domain("the-domain-to-check.com");
// Returning the full domain name
echo $my_domain->get_fulldomain(); // Will return "the-domain-to-check.com"
2.9 is_valid() :: validation of a domain name
=============================================
This function checks if a domain name is valid or not
include("domain.class.php");
// Initializing domain class
$my_domain=new domain("the-domain-to-check.com");
// Is domain valid or not
if($my_domain->is_valid()==true){
echo "Domain name is valid";
}else{
echo "Domain name is not valid";
}
!Attention:
If you want to have the full IDN support, you cant use
this function to check it. Only several of the IDN chars
will be supported yet.
2.10 get_tlds() :: all supported top level domains
=================================================
This function returs all supported top level domains in an array.
include("domain.class.php");
// Initializing domain class
$my_domain=new domain("the-domain-to-check.com");
// Printing out all supported top level domains
$tlds=$my_domain->get_tlds();
for($i=0;$i
