PHP

PHP is a server-side programming language widely used in web development. PHP code runs on the server and can process requests, access databases, manage sessions, and generate HTML or other response formats. Content management systems such as WordPress and frameworks such as Symfony are built with PHP.

The language alone does not make an application secure or insecure. Quality depends on architecture, input validation, output encoding, permissions, dependencies, tests, and a supported PHP version. Outdated runtimes and libraries should be upgraded. Established standards, package management, and automated checks are important foundations for new projects.

• Server-side processing of web requests
• Dynamic output and database access
• Large ecosystem of CMS platforms and frameworks
• Maintain supported versions and dependencies
• Security depends on correct implementation
