Download the response and analyze the output. We will create a function which connects to the whois server using socket connection. ![]() The output show us whether the domain is registered or not.Īfter the short introduction let’s create some code. To get information about the actual domain name we will send a request to the whois server and then we will process the output. There can be more whois server for the actual tld. In general all top level domain (usually just called tld) has its own whois server. ![]() DOMAIN AVAILABILITY CHECKER PHP SCRIPT REGISTRATIONWhen you want to check whether a given domain name is available or not you have to send a request to a whois server which maintains domain registration details for the actual domain. com domains but you can extend the script to handle as many top level domains as you want. DOMAIN AVAILABILITY CHECKER PHP SCRIPT HOW TOthe tip is out there now anyway.In this tutorial I will show you how to create a PHP script to check whether the actual domain name is available or not. probably would be more efficient if it checked $try_a before making the query, but this works for me so I'll leave that up to someone else to implement in their own work. They are made to replace gethostbyname, in a way that if $try_a is true, if it fails to get AAAA records it will fall back on trying to get A records.įeel free to correct any errors, I realise that it is asking for *both* A and AAAA records, so this means two DNS calls. I don't believe this issue has been addressed yet. I have written two functions to implement this. Gethostbyname and gethostbynamel does not ask for AAAA records.
