The impact of PHP 7 and above on the PHP framework

PHP 7 and higher bring significant changes that impact the performance, security, syntax, and libraries of the PHP framework: Performance improvements: Zend engine optimizations and scalar type hints enhance code execution speed and memory utilization Rate. Security improvements: New password hashing functions and enhanced input validation improve application security. Syntax improvements: Exception handling and return value type declaration mechanisms improve code readability and type safety. Library improvements: New convenience functions simplify array operations, and the password_hash() function provides secure password generation. Practical case: Taking the Laravel framework as an example, the improvements in PHP 7 simplify the routing syntax and improve readability.

The impact of PHP 7 and above on the PHP framework

Preface

The release of PHP 7 and above brings significant changes and improvements to the PHP framework. These changes affect the framework's performance, security, syntax, and function libraries, creating new possibilities and challenges for developers.

Performance improvements

• Zend engine optimization: PHP 7 introduces optimization of the Zend engine to improve code execution speed and memory Utilization.
• Scalar type hints: PHP 7.0 introduced scalar type hints, allowing the type of variables to be declared. This helps detect type errors at compile time and improves performance.

Security Improvements

• Password Hash Functions: PHP 7.2 introduced new password hash functions, such as argon2id , providing a more secure way to store passwords.
• Input validation: PHP 7.2 introduces an improved version of the filter_var() function, providing more powerful input validation functionality.

Syntax improvements

• Exception handling: PHP 7 introduced an exception handling mechanism to allow developers to better handle Errors and exceptions.
• Return value type declaration: PHP 7.0 allows the declaration of the return value type of a function, which helps improve the type safety of the code.

Function library improvements

• Convenience functions: PHP 7 introduces new convenience functions, such as array_column() and array_filter(), simplifies array operations.
• Password generation: PHP 7.0 introduced the password_hash() function, providing secure and easy-to-use password generation.

Practical case

The following example demonstrates the impact of PHP 7 on the Laravel framework:

// Laravel 6.0
Route::get('/users', 'UserController@index')->middleware('auth');

// Laravel 8.0
Route::get('/users', [UserController::class, 'index'])->middleware('auth');

In Laravel 8.0, Closure routing syntax Replaced by shorter, more readable class method syntax.

Conclusion

PHP 7 and above have had a profound impact on the PHP framework, improving performance, security and readability. By adopting these improvements, developers can create more efficient and secure applications.
