Why Manage PHP Versions on Linux

As development projects diversify, different projects may require different PHP versions. Proper PHP version management can prevent environment conflicts and keep the development setup clean and efficient. Therefore, mastering PHP version switching techniques is essential for developers.

Main PHP Version Management Tools

PHP Version Switcher (phpenv)

phenv is a lightweight and flexible PHP version management tool that makes installing and switching between multiple PHP versions easy. Below are the common installation and usage steps:

# Install phpenv
git clone https://github.com/phpenv/phpenv.git ~/.phpenv
echo 'export PATH="$HOME/.phpenv/bin:$PATH"' >> ~/.bashrc
echo 'eval "$(phpenv init -)"' >> ~/.bashrc
exec $SHELL

# Install specific PHP versions
phpenv install 7.4.16
phpenv install 8.0.3

# Switch PHP version
phpenv global 7.4.16
php -v

Homebrew (for macOS and Linux)

Homebrew is a convenient package manager supporting installation and management of multiple PHP versions, suitable for macOS and some Linux distributions. Usage example:

# Install Homebrew
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"

# Install PHP versions
brew tap shivammathur/php
brew install shivammathur/php/[email protected]
brew install shivammathur/php/[email protected]

# Switch PHP version
brew unlink [email protected]
brew link [email protected]
php -v

Using Docker for PHP Version Isolation

Docker enables creating isolated runtime environments per project, specifying the PHP version needed, greatly enhancing version isolation and environment consistency. Example:

# Create Dockerfile
FROM php:8.0-apache

# Install extensions
RUN docker-php-ext-install mysqli

# Copy project files
COPY src/ /var/www/html/

Conclusion

This article introduced three practical methods for managing PHP versions on Linux: phpenv, Homebrew, and Docker. These tools allow developers to easily install and switch PHP versions, avoid version conflicts, and improve project stability and development efficiency. Choosing the right tool based on your needs will help you better maintain your development environment and enhance your overall coding experience.
