How to Force Composer to Use a Specific PHP Version on 1and1 Hosting?

Overcoming PHP Version Discrepancies with Composer on 1and1 Hosting

When working with 1and1 hosting, users may encounter difficulties installing Composer due to PHP version discrepancies. Initially, using "php composer.phar install" results in PHP 4.4.6, an insufficient version. While "php5.5 composer.phar install" provides some progress, it ultimately fails due to subsequent PHP calls reverting to 4.4.6. This article aims to resolve this issue by guiding you in instructing Composer to utilize a specific PHP version.

Resolution:

To resolve this issue, replace the standard Composer command with a modified one that forces the use of the desired PHP version. For Ubuntu 18.04 users, the following command has been found to work:

/usr/bin/php7.1 /usr/local/bin/composer update

Ensure to replace "php7.1" with the desired PHP version you wish Composer to use. This command explicitly specifies the PHP version to be used, ensuring that Composer runs with the correct configuration. By following this approach, you can overcome PHP version discrepancies and successfully install Composer on 1and1 hosting.
