$ export COMPOSER_PLATFORM=8.3.0<\/code><\/pre>\n\n\n\nStep 2: Run Composer Commands<\/h4>\n\n\n\n With the environment variable set, Composer will use the specified PHP version for its operations:<\/p>\n\n\n\n
$ composer install<\/code><\/pre>\n\n\n\nMethod 3: Using PHP Aliases<\/h3>\n\n\n\n You can create an alias for the desired PHP version and use it with Composer.<\/p>\n\n\n\n
Step 1: Create a PHP Alias<\/h4>\n\n\n\n Add the alias to your shell configuration file (~\/.bashrc<\/code>, ~\/.zshrc<\/code>, etc.):<\/p>\n\n\n\nalias php=php8.3<\/code><\/pre>\n\n\n\nReplace php8.3<\/code> with the desired PHP version.<\/p>\n\n\n\nStep 2: Reload Shell Configuration<\/h4>\n\n\n\n Reload your shell configuration to apply the alias:<\/p>\n\n\n\n
$ source ~\/.bashrc<\/code><\/pre>\n\n\n\nStep 3: Run Composer Commands<\/h4>\n\n\n\n With the alias set, you can run Composer commands, and the specified PHP version will be used:<\/p>\n\n\n\n
$ composer install<\/code><\/pre>\n\n\n\nMethod 4: Using the composer<\/code> Command with a Specific PHP Binary<\/h3>\n\n\n\nYou can directly specify the PHP binary when running Composer commands.<\/p>\n\n\n\n
Step 1: Run Composer with Specific PHP Binary<\/h4>\n\n\n\n Use the desired PHP binary to run Composer commands:<\/p>\n\n\n\n
$ php8.3 \/usr\/local\/bin\/composer install<\/code><\/pre>\n\n\n\nReplace php8.3<\/code> with the path to the desired PHP version binary and \/usr\/local\/bin\/composer<\/code> with the path to your Composer binary.<\/p>\n\n\n\nExample Scenario<\/h2>\n\n\n\n Let’s say you have PHP 8.2 and PHP 8.3 installed on your system, and you need Composer to use PHP 8.2 for a specific project.<\/p>\n\n\n\n
\nUsing composer.json<\/code>:<\/strong>{ "config": { "platform": { "php": "8.2.0" } } } <\/code> Run:$ composer install<\/code><\/li>\n\n\n\nUsing Environment Variables:<\/strong>$ export COMPOSER_PLATFORM=8.2.0 composer install<\/code><\/li>\n\n\n\nUsing PHP Aliases:<\/strong> Add to ~\/.bashrc<\/code>:$ alias php=php8.2 <\/code>Reload:$ source ~\/.bashrc composer install<\/code><\/li>\n\n\n\nUsing Specific PHP Binary:<\/strong>$ php8.2 \/usr\/local\/bin\/composer install<\/code><\/li>\n<\/ol>\n\n\n\nConclusion<\/h2>\n\n\n\n Forcing Composer to use a specific PHP version is essential when managing projects with different PHP version requirements.
