What is PHP
PHP scripts are executed on the server side, which means that they run on a web server before the final HTML is sent to the client’s browser. This allows developers to create dynamic web pages, handle form data, interact with databases, and perform a wide range of server-side tasks.
Key features of PHP include:
Embedding in HTML: PHP code can be embedded directly within HTML, allowing developers to mix server-side logic with client-side markup.
Database Interaction: PHP can easily connect to various database systems, such as MySQL, PostgreSQL, and SQLite, enabling the creation of dynamic web applications that store and retrieve data.
Form Handling: PHP can process form data submitted by users and generate appropriate responses, such as displaying error messages or storing data in a database.
Session Management: PHP supports session management, which allows the tracking of user interactions across multiple pages and visits.
File Manipulation: PHP provides functions for reading, writing, and manipulating files on the server’s file system.
Security: PHP offers various security features to help prevent common web vulnerabilities, such as cross-site scripting (XSS) and SQL injection.
Modularity: PHP supports the use of functions, classes, and libraries, making it easier to organize and reuse code.
Community and Libraries: PHP has a large and active community, which has led to the development of a vast ecosystem of libraries, frameworks (such as Laravel, Symfony, and CodeIgniter), and tools that simplify and accelerate web development.
