Modern php new features and good practices pdf

Here are some modern PHP features and good practices that you can learn from:

Modern PHP Features:

  1. Type Declarations: PHP 7.0 introduced type declarations for function parameters and return types. This helps catch type-related errors at compile-time.
  2. Return Type Declarations: PHP 7.0 also introduced return type declarations for functions. This helps ensure that functions return the expected type of value.
  3. Scalar Type Hints: PHP 7.0 introduced scalar type hints for function parameters, which allows you to specify the type of value that a function parameter should be.
  4. Null Coalescing Operator: PHP 7.0 introduced the null coalescing operator (??), which returns the first operand if it exists and is not null, and the second operand if the first operand is null.
  5. Spaceship Operator: PHP 7.0 introduced the spaceship operator (<=>, <=<), which is used to compare two values and return -1, 0, or 1 based on the comparison.
  6. Generator Functions: PHP 5.5 introduced generator functions, which allow you to create iterators that can be used to iterate over a sequence of values.
  7. Anonymous Classes: PHP 7.0 introduced anonymous classes, which allow you to create classes without a name.
  8. Closure Type Hints: PHP 7.0 introduced closure type hints, which allow you to specify the type of value that a closure should return.

Good Practices:

  1. Use Composer: Composer is a popular package manager for PHP that allows you to easily install and manage dependencies for your projects.
  2. Use PSR-12: PSR-12 is a coding standard for PHP that provides guidelines for writing clean, readable, and maintainable code.
  3. Use a PHP Framework: PHP frameworks such as Laravel, Symfony, and CodeIgniter provide a structured way of building web applications and can help you follow best practices.
  4. Use a PHP IDE: PHP IDEs such as PhpStorm, NetBeans, and Sublime Text provide features such as code completion, debugging, and code analysis that can help you write better code.
  5. Use a Version Control System: Version control systems such as Git allow you to track changes to your code and collaborate with others.
  6. Write Unit Tests: Writing unit tests for your code can help you ensure that it works correctly and catch bugs early.
  7. Use a Code Sniffer: Code sniffers such as PHP-CS-Fixer can help you identify and fix coding standards violations in your code.
  8. Use a PHP Security Framework: PHP security frameworks such as OWASP PHP Security Cheat Sheet provide guidelines and tools for securing your PHP applications.
