What are some best practices for managing multiple PHP versions on a server to avoid conflicts and ensure smooth operation of applications?

Managing multiple PHP versions on a server can be achieved by using tools like PHP version managers such as PHPBrew or Docker containers. These tools allow you to easily switch between different PHP versions, isolate dependencies, and avoid conflicts that may arise when running multiple applications with different PHP requirements on the same server. ```bash # Install PHPBrew curl -L -O https://github.com/phpbrew/phpbrew/raw/master/phpbrew chmod +x phpbrew sudo mv phpbrew /usr/local/bin/phpbrew # Install PHP versions using PHPBrew phpbrew init phpbrew lookup-prefix homebrew phpbrew install php-7.4 +default phpbrew install php-8.0 # Switch between PHP versions phpbrew switch php-7.4 phpbrew switch php-8.0 ```
