If you want to create web applications you need to learn the following languages: Javascript, PHP, HTML, CSS and SQL. It sounds awesome right? But in fact it is not. Within one week and having mastered the “basics” of each of the above-mentioned languages, you’ll be able to write basic web-applications with ease. Believe me. It really is that easy!

PHP is the foundation of your web application. This is the language that is installed on the web
server. In regards to this language, it’s not the only choice as you can choose from others but the basics remain in most all cases. At minimum you need to know HTML, CSS and Javascript. It’s also wise to learn to keep up with the masses as 99% of web programmers learn SQL in able to communicate or “talk“ to the sites database. However, there are quite a few other programming languages that can perform the same tasks on par with PHP.

It’s best to start with learning these two presentation languages: HTML and CSS as both of these languages are complementary to each other. HTML without CSS is ineffective and vice versa since the HTML language is responsible for the structure as well as content of the web page when displayed in the visitors browser. For example, it indicates that the contact form goes right after the paragraph and has one field for e-mail and another field for the user name which is typically what you’d find on just about any website these days.

The CSS language is responsible for the overall appearance of an web page when it’s displayed in a visitors browser. For example, what font type, size, colors, objects to present on the page, thickness should be used when displaying the frames and what should be the indent from each edge of the elements.

Next you’ll want to start learning the language of data storage called SQL, which allows access the database of stored information such as visitor names, e-mail addresses, etc. For example, using SQL,you can access the database to store e-mail addresses and user name by specifying the command “INSERT INTO visitors (name, email) values (‘Mark Maunder’, ‘[email protected]’); other ways to create database stores, the common name for which is NoSQL. Such databases and repositories began to form in the last 4 years and their creators sow fear and doubt about the use of SQL thereby leaving novices such as yourself to the trouble. The reality is this: 99% of web applications used SQL and continue to use it. This language works, it’s fast, easy to learn, everyone is able to understand it. SQL is widely used by WordPress, Wikipedia, Facebook and most others that use databases regardless of whether they like this language or not. Just learn SQL !! I also strongly advise you to use MySQL to store the information of your web applications (even though MySQL belongs to Oracle), since it is the most popular database with open source. Applications written in PHP use MySQL more often than any other “database engine“ in the world.

So, let’s sum up what you should learn:
Javascript (programming language installed inside the Internet browser of your site's visitor)
PHP (the programming language installed on the server)
HTML (presentation language responsible for displaying the structure of the page in the
browser)
CSS (presentation language that is responsible for the appearance of the web page)
SQL (a data access language that allows you to store and restore information from a database).
