Changing PHP Version in Symfony

To change the PHP version in Symfony, you need to update the PHP version specified in your project's composer.json file. Here are the steps to follow:

1. Open your project's composer.json file.
2. Locate the "require" section.
3. Look for the "php" key-value pair and update the PHP version to the desired version.
4. For example, if you want to use PHP 7.4, change "php": "^7.2" to "php": "^7.4".
5. Save the changes to the composer.json file.
6. Run the following command in your project's root directory to update the dependencies: composer update This will update the PHP version used by Symfony to the one specified in the composer.json file.

Please note that changing the PHP version may require additional steps, such as installing the corresponding PHP version on your system or configuring your web server to use the new PHP version. Make sure to consult the Symfony documentation or relevant resources for more detailed instructions specific to your setup.
