![]() PHP then uses the code in the file and the data from the database to create the HTML that browsers require to display web pages. PHP also communicates with MySQL to fetch any data referenced in the code. If the request is for a PHP file, Apache passes the request to PHP, which loads the file and executes the code contained in the file. The process starts when the Apache web server receives requests for web pages from a user’s browser. ![]() Although PHP is nominally at the top or presentation layer, the PHP component sits inside Apache.Ī high-level look at the LAMP stack order of execution shows how the elements interoperate. The next layer is Apache and MySQL, followed by PHP. LAMP has a classic layered architecture, with Linux at the lowest level. If you prefer, you can swap out PHP in favor of Perl or the increasingly popular Python language. It makes programming easier-and a bit more fun-by allowing you to write new code, hit refresh, and immediately see the resulting changes without the need for compiling. To provide this type of functionality, you simply drop PHP code into the parts of a page that you want to be dynamic. You cannot use HTML to perform dynamic processes such as pulling data out of a database. PHP: The programming language. The PHP open source scripting language works with Apache to help you create dynamic web pages.NoSQL Databases: What's the Difference?" for more information on SQL and NoSQL databases. MySQL is suitable for running even large and complex sites. See " SQL vs. SQL is a great choice if you are dealing with a business domain that is well structured, and you want to translate that structure into the backend. With My SQL, you can store all your information in a format that is easily queried with the SQL language. MySQL: The database. MySQL is an open source relational database management system for storing application data.Developed and maintained by an open community, Apache is a mature, feature-rich server that runs a large share of the websites currently on the internet. Apache: The web server. The Apache web server processes requests and serves up web assets via HTTP so that the application is accessible to anyone in the public domain over a simple web URL.Linux is popular in part because it offers more flexibility and configuration options than some other operating systems. Today, it has an extensive worldwide user base that extends across industries. Linux: The operating system. Linux is a free and open source operating system (OS) that has been around since the mid-1990s.Each component contributes essential capabilities to the stack: Together, they provide a proven set of software for delivering high-performance web applications. LAMP stands for Linux, Apache, MySQL, and PHP.
