Domain Names, sometimes called “dot coms” although not limited to the .com extension, have been around since the early days of the internet. Thanks to being very cheap, it can be difficult to acquire a domain name that matches your purpose, and even more difficult to acquire a domain name that matches your business. Sometimes you have to be tricky, or use extra words to find a good domain name. Sometimes you just have to break out your wallet and pay good money for a good domain name, which can run anywhere from several hundred dollars to several thousand dollars. Record-setting sales of domain names have reached multi-million dollar values. But you don’t need one of those domains, most people can get by with a less expensive domain. The value of a domain doesn’t only come from the words it contains, but from the content, traffic and internet presence associated with that domain. You can take a cheap $10 domain name, and over time give it great value by building a solid content profile, promoting it and increasing traffic, and promoting it’s overall online presence.

Glossary: SLD and ccSLD (Second Level Domain, and country code SLDs)

by php-love

A SLD or “Second Level Domain” is all often called the “domain” or “base domain.”

Most of the time when people buy a domain, they are buying a Second Level Domain. To get even more specific, they are buying a SLD + TLD combination.

When a ccSLD – or “country code Second Level Domain” – is used, then a user will actually be buying a third level domain.

ccSLDs can make it difficult for developers to deal with domains, in the sense that many developers have to parse out URLs for many reasons, but there is no hard set rule on how to parse a domain out. You just have to have a comprehensive list of all ccSLDs and their corresponding ccTLDs in order to properly distinguish the users “base domain” from their “domain extension.”

Glossary: Domain Extension (aka. TLD, ccTLD and ccSLD)

by php-love

A “domain extension” is slang for “Top Level Domain” or “country code Second Level Domain + country code Top Level Domain”.

In other words, if you buy “example.com” – “example” is your “base domain” and “.com” is your domain extension. In this case, your base domain is your “Second Level Domain” and your domain extension – “.com” is your TLD.

On the other hand, if you buy “example.co.uk” then “example” is still your base domain but “.co.uk” is your “domain extension”. In this case, your “base domain” is your “Third Level Domain”, and your “domain extension” – “.co.uk” – is your SLD + TLD.

Glossary: TLD and ccTLD (Top Level Domain, and country code TLDs)

by php-love

A “TLD” or “Top Level Domain” is also commonly known as a “domain extension.”

We actually just prefer the term “domain extension.”

Examples of TLDs are:

.com
.net
.org

Examples of ccTLDs are:

.uk
.au

A ccSLD – or country code Second Level Domain, is often mistaken for a TLD, however they are actually two separate domain levels. For example “.co.uk” is two domains: “.co” os a ccSLD and “.uk” is a ccTLD.

See SLDs and ccSLDs.

How do I parse out the subdomain from the TLD in PHP?

by php-love

How do I use PHP’s parse_url() function to separate out the base domain from the domain extension?
How do I use PHPto extract the domain from a URL?
How do I extract the domain when it is using a ccSLD, or “country code second level domain”, such as .com.au and .co.uk?

PHP’s parse url function is quite handy, but not all powerful, and it cannot distinguish between domains and subdomains. (more…)
