PHP is a general yet powerful scripting language which is used to develop web applications. It's one of the most popular server-side web development programming languages in the web development industry. More than 20 million websites are running on PHP and it is being installed on over 1 Million web servers around the globe, and the numbers only keep increasing.
PHP can be installed on various operating systems including the major server OS systems such as Linux, Windows, UNIX as well as on Mac systems. One reason why PHP is so popular is because it's distributed under a Free License.
MySQL
MySQL is a widely used Relational Database Management System (RDBMS). Currently Internet giants such as Google, Facebook, Wikipedia, YouTube and Flickr are using MySQL for their major development projects. ORACLE owned MySQL has proved its stability in operation over the last few years and has won the hearts of the Web developers around the word with its easy to manage and reliable functionality.
PHP & MySQL are one of the most popular combinations for database driven web development projects and PHP has a fully featured component library to support interaction with MySQL databases. Facebook.com is one of the best examples which uses this technological combination and is very successful in its operation.
HTML/CSS
While PHP & MySQL do their best in Business logics, Controls and Data storing, a web project should also be appealing to its users and should be successful in winning its users by having a good look and clever presentation of data/information. This is where HTML & CSS come into action. Data in a MySQL database is processed/controlled by PHP according to your business logics and presented to your users' web browser using HTML/CSS.
HTML (Hyper Text Markup Language) is also a programming language which is understood by your web browser. An HTML document holds the structure of a web page, such as text, images, lists and data tables. In the early days all the contents on an HTML document were formatted (Bold text, Headings, etc...) on the same document using special HTML tags. But with the introduction of CSS it all shifted into a new era of web designing.
A CSS (Cascading Style Sheets) document holds information such as page layout, text color, background color, positions of elements etc. The idea of CSS was to separate the content (Text, Images) of an HTML document from its presentation semantics. Over the years usage of CSS in web pages increased and it became a very powerful tool in web designing. CSS played a big roll in the introduction of Web 2.0, which took the web designing trend to a whole new level.
As you can see, combining PHP/MySQL with HTML/CSS can take your project to the next level. If you use this combination of technologies in your project, it's guaranteed that you will be rewarded with the following,
• Low development/maintenance cost
• Less Time consumption in development
• Super fast application functionality
• Easily accessible help (Multilingual Documentations, Online Community)
• New developers can easily be familiar with codes
• Platform independence
• Less time consumption in deployment.
