4 minutes read

To install PHP 8 on XAMPP, you will need to download the latest version of PHP 8 from the official PHP website. Once you have downloaded the PHP 8 files, you will need to extract them to a directory on your computer.


Next, navigate to the XAMPP installation directory on your computer and locate the "php" folder. Rename the existing "php" folder to something like "php_old" to keep it as a backup.


Copy the extracted PHP 8 files into the XAMPP "php" folder. Make sure to replace any existing files when prompted.


After copying the PHP 8 files into the XAMPP "php" folder, you will need to configure XAMPP to use PHP 8. Open the XAMPP control panel and stop the Apache server. Then, click on the "Config" button next to Apache and select "PHP (php.ini)" from the dropdown menu.


In the php.ini file, locate the line that reads "extension_dir =" and update it to point to the new PHP 8 extension directory within the XAMPP installation folder. Save the changes and restart the Apache server in the XAMPP control panel.


Finally, open a web browser and navigate to "localhost" to test that PHP 8 is successfully installed on your XAMPP server. You should see the PHP information page displaying the PHP 8 version.


Congratulations, you have successfully installed PHP 8 on XAMPP!

What is the difference between PHP 7 and PHP 8?

PHP 8 is the latest version of the PHP programming language, released in November 2020. There are several key differences between PHP 7 and PHP 8, including:

  1. Performance improvements: PHP 8 offers significant performance improvements over PHP 7, with some benchmarks showing up to a 4x increase in performance.
  2. JIT compiler: PHP 8 includes a Just-In-Time (JIT) compiler, which can further improve performance by compiling PHP code into machine code for faster execution.
  3. Union types: PHP 8 introduces union types, which allow developers to specify that a function parameter can accept multiple different types.
  4. Named arguments: PHP 8 allows developers to pass function arguments by using the name of the parameter, rather than its position. This can make code more readable and maintainable.
  5. Attributes: PHP 8 introduces attributes, which provide a way to add metadata to classes, methods, and properties in a more structured and standardized way compared to PHP 7's comment-based annotations.
  6. Constructor property promotion: PHP 8 includes a new syntax for defining and initializing class properties in a constructor, making it easier to create and maintain classes with many properties.


These are just a few of the key differences between PHP 7 and PHP 8. Overall, PHP 8 offers improved performance, new features, and syntax improvements that make it a worthwhile upgrade for many PHP developers.
