PHP What is php? PHP (Hypertext Preprocessor) is a widely-used open-source scripting language that is especially suited for web development and can be embedded into HTML. Here鈥檚 a breakdown:
Server-Side Scripting: PHP code is executed on the server, and the results are sent to the user鈥檚 web browser as HTML. This contrasts with client-side scripting languages like JavaScript, which are executed in the browser. Dynamic Web Pages: PHP allows you to create dynamic web pages that can change content based on user input, database information, or other factors. Database Interaction: PHP can connect to various databases (like MySQL, PostgreSQL, and Oracle) to store and retrieve data. This is essential for building web applications that require data management. Open Source: PHP is open-source, meaning it鈥檚 free to use and distribute. This has contributed to its widespread adoption. Cross-Platform: PHP runs on various operating systems, including Windows, Linux, and macOS. Uses: Building websites and web applications Developing e-commerce platforms Creating content management systems (CMS) like WordPress, Drupal, and Joomla Handling form data Generating dynamic page content.
