PHP is a server-side scripting language designed for web development but also used as a general-purpose programming language. A popular open source server side scripting language that is the basis of many applications including WordPress, Joomla and Drupal. PHP is a widely-used general-purpose scripting language that is especially suited for Web development and can be embedded into HTML. PHP code can be simply mixed with HTML code, or it can be used in combination with various templating engines and web frameworks. PHP code is usually processed by a PHP interpreter, which is usually implemented as a web server's native module or a Common Gateway Interface (CGI) executable. After the PHP code is interpreted and executed, the web server sends resulting output to its client, usually in form of a part of the generated web page
PHP(Hypertext Preprocessor) is a fast and feature-rich open source scripting language used to develop Web Applications or Internet / Intranet Applications. MySQL is a powerful open source database server built based on a relational database management system (RDBMS) and is capable of handling a large concurrent database connection. When combined together, talented PHP and MySQL developers can build very powerful and scalable Web / Internet / Intranet Applications.PHP and MySQL are referred to as development tools.
PHP and MySQL are Open Source, meaning that they are free development tools, and there is a large community of dedicated volunteer programmers who contribute to make improvements and are continuously adding features to it. The development tools and database servers that require licensing costs have limited programming resources compared to open source development tools, which have an enormous and fast growing dedicated and knowledgeable community that extends around the world. There has been disagreement about which tool is better. Naturally, the developer who is more familiar with one tool over the other will stand behind the tool that he or she has experience with. With our experience, we have found that, PHP and MySQL are the best development tools. When developed correctly, applications can be built with clean and simple usability, complex functionality, speed, power and scalability
MySQL is a popular choice of database for use in web applications, and is a central component of the widely used LAMP open source web application software stack. LAMP is an acronym for "Linux, Apache, MySQL, Perl/PHP/Python." Free-software-open source projects that require a full-featured database management system often use MySQL. Many of the world's largest and fastest-growing organizations including Facebook, Google, Adobe, Alcatel Lucent and Zappos rely on MySQL to save time and money powering their high-volume Web sites, business-critical systems and packaged software.
