How to choose php version for composer?

Question

linux

The server has php5.6 installed by default, but 7.4 is also available. I want composer to run with it. Or make an alias. Tried to do like this:

/usr/local/bin/composer_php7.4

#!/bin/bash
/opt/php74/bin/php /usr/local/bin/composer

But that's not how the parameters are thrown...

Answer 1

You can add it to the ~/.bash_profile file (if needed for one user) or to the /etc/profile file (if needed for all users on the server):

export PATH=/opt/php74/bin/:$PATH
alias composer='/opt/php74/bin/php /usr/local/bin/composer'

Then relogin. Ready.

Answer 2

find out the paths in the folder where you work with composer
