Hello world!

September 29, 2006

In the computer language world, the phrase “Hello world” is used basically for testing especially when using an echo function. For example, in Javascript you would write this:

document.write("Hello world!");

For PHP, it would be this:

echo("Hello world!");

It is even used for markup languages like HTML:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd&gt;
<title>Hello world!</title>
<p>Hello world!</p>

If you really want to know all of them, Wikipedia actually has an article for them properly called “Hello world program“.

Nevertheless, the real point of this post is to say hello to you (even though you’re probably the only person that ever read this). Hopefully, this blog will grow and accumilate hundreds of posts. But as the old saying goes, “A journey of a thousand miles begins with a single step.”
