PHP 7 Assessment Test

A PHP 7 Assessment Test evaluates an individual's proficiency in using PHP (Hypertext Preprocessor) version 7, which is a widely-used open-source scripting language primarily designed for web development.

A PHP 7 Assessment Test evaluates candidates for:

1. PHP Basics:
   • Understanding of PHP syntax, variables, data types, operators, control structures (e.g., if-else, loops), functions, and error handling mechanisms.
2. PHP 7 Features:
   • Knowledge of new features introduced in PHP 7.x releases, such as scalar type declarations (int, float), return type declarations, null coalescing operator (??), spaceship operator (<=>), and anonymous classes.
3. Object-Oriented Programming (OOP):
   • Proficiency in OOP concepts in PHP, including classes, objects, inheritance, encapsulation, polymorphism, interfaces, traits, and namespaces.
4. Exception Handling:
   • Skills in using try-catch blocks and throwing exceptions to handle errors and exceptional conditions in PHP applications.
5. Web Development with PHP:
   • Experience in developing web applications using PHP, including handling HTTP requests and responses, form handling, session management, cookies, and URL manipulation.
6. Database Integration:
   • Knowledge of integrating PHP with databases using MySQLi (MySQL Improved) or PDO (PHP Data Objects), performing CRUD operations, transactions, and prepared statements to ensure security and efficiency.
7. PHP Security Best Practices:
   • Awareness of common PHP security vulnerabilities (e.g., SQL injection, XSS attacks, CSRF attacks) and techniques to mitigate these risks, including input validation, output sanitization, and parameterized queries.
8. PHP Frameworks:
   • Familiarity with popular PHP frameworks such as Laravel, Symfony, CodeIgniter, and Zend Framework, including their features, architecture, and best practices for web application development.
9. PHP Libraries and Tools:
   • Experience in using PHP libraries and tools for common tasks such as file handling, image manipulation, PDF generation, caching, logging, and unit testing (e.g., PHPUnit).
10. API Development:
    • Proficiency in developing and consuming RESTful APIs using PHP, implementing API endpoints, handling requests and responses (JSON/XML), authentication mechanisms, and API documentation.
11. Performance Optimization:
    • Skills in optimizing PHP code for performance, including code profiling, caching strategies (e.g., opcode caching with APCu or OPcache), minimizing database queries, and reducing file system operations.
12. Deployment and Version Control:
    • Understanding of deploying PHP applications to web servers (e.g., Apache, Nginx), configuring PHP settings, managing dependencies with Composer, and using version control systems (e.g., Git) for collaborative development.

The PHP 7 Assessment Test assesses candidates' abilities to develop robust and efficient web applications using PHP 7, incorporating modern features, adhering to best practices, and ensuring security and performance optimizations across different stages of development and deployment.
