HTML is the code used to make websites.

PHP is the code used to make HTML that changes.

For example, you could make an HTML file that says "It is 1 AM."

But at 3 PM, it would still say the same thing.

You can use PHP to make a file that says:

It is (TIME) (AM/PM).

Whenever your browser requests the HTML, the server figures out the time, and generates an HTML page based on that saying:

It is 3 PM.

XML is similar to HTML, but it can't do websites. It CAN do RSS feeds, word documents, or anything else, but you have to build a program that knows how to read the type of XML you're doing.

SQL is a database system, that can be used to store information in sets of tables. For example, say you have a website that stores phone numbers of people. You can build an SQL database with two tables: Male and Female. All the numbers and names of girls get put in the female, and the guys in the male. You can put hundreds of tables with any name, and the tables can be as big as you want. Good for storing information for something like Yahoo answers. They probaby store the questions and answers in a sql database.

You can retrieve info from an SQL database using PHP.

The bottom line: PHP, HTML, SQL, and (possibly) XML are all building blocks to a website. PHP generates the HTML, SQL provides the information to put in the page, HTML tells the browser how the page should look. I don't know much about XML.

HTML and XML have similarities. They both present
information or data in an abstract descriptive way.
Although XML goes far beyond of HTML.

PHP is a programming language not just a document
description. It's often used on the server side of web
applications. Think about content production or AJAX.
Although none of this requires PHP. You could as well
do it in JSP or Perl.

SQL is a type of database storage. It's not really related
to any of the other in a special way other than that you
can use it with PHP.
