To change the PHP version in a Symfony 4 project, you need to follow these steps:

  1. Ensure you have the desired PHP version installed on your system. You can check the installed PHP versions by running the following command in your terminal: $ php -v
  2. Update your Symfony project's composer.json file in the project's root directory. In the require section, update the php version constraint to the desired version. For example, if you want to use PHP 7.4, change it to: "require": { "php": "^7.4", // ... },
  3. Save the changes to the composer.json file.
  4. In your terminal, navigate to the project's root directory and run the following command to update your project's dependencies: $ composer update This will install the necessary dependencies for the project, including the updated PHP version specified in the composer.json file.
  5. Once the dependencies have been updated, you can verify the PHP version by running the following command in your terminal: $ php -v It should display the desired PHP version.


You have now successfully changed the PHP version in your Symfony 4 project.
