Run composer commands with different php versions
I have two php versions installed on my system php 5.3 and php 5.6 When running commands in cmd for version check i got this :
php -v
PHP 5.3.28 (cli) (built: Dec 10 2013 22:27:36)
Copyright (c) 1997-2013 The PHP Group
Zend Engine v2.3.0, Copyright (c) 1998-2013 Zend Technologies
and for php 5.6
php56 -v
PHP 5.6.17 (cli) (built: Jan 6 2016 13:28:21)
Copyright (c) 1997-2015 The PHP Group
Zend Engine v2.6.0, Copyright (c) 1998-2015 Zend Technologies
I have path setup for both of these in my environment. Now while running composer create-project i get error because composer points to php 5.3 and laravel requires php >= 5.5
composer create-project laravel/laravel BlogSys
Installing laravel/laravel (v5.0.22)
- Installing laravel/laravel (v5.0.22)
Loading from cache
Created project in BlogSys
Loading composer repositories with package information

Problem 1
- Installation request for jeremeamia/superclosure 2.1.0 -> satisfiable by jeremeamia/SuperClosure[2.1.0].
- jeremeamia/SuperClosure 2.1.0 requires php >=5.4 -> your PHP version (5.3.28) does not satisfy that requirement.
Problem 2
- Installation request for laravel/framework v5.0.16 -> satisfiable by laravel/framework[v5.0.16].
- laravel/framework v5.0.16 requires php >=5.4.0 -> your PHP version (5.3.28) does not satisfy that requirement.
Problem 3
- Installation request for league/flysystem 1.0.2 -> satisfiable by league/flysystem[1.0.2].
- league/flysystem 1.0.2 requires php >=5.4.0 -> your PHP version (5.3.28) does not satisfy that requirement.
When i want to run this composer command appending php or (php56) before composer i got this error
php composer create-project laravel/laravel BlogSys
Could not open input file: composer
How can i impose composer to execute its command using specific version of php?

@helwieahmad Thanks for the link. But what I comprehended is this that it'll simply force Laravel to install even if it doesn't meet the requirements of local machine.
--ignore-platform-reqs: ignore php, hhvm, lib-* and ext-* requirements and force the installation even if the local machine does not fulfill these. See also the platform config option.

Know this question is a bit old... but if you pull down composer into your app root:
https://getcomposer.org/download/
Instead of relying on global composer, then you can run:
php56 composer.phar {your command}
or I believe newer homstead versions would be like:
php7.1 composer.phar {your command}

This might help some... composer is likely to be using /usr/bin/php, consider the following:-
$ which php
/usr/bin/php
$ /usr/bin/php -v
PHP 7.1.33
$ php -v
PHP 7.2.24
$ type -a php
php is aliased to '/usr/bin/php7.2'
php is /usr/bin/php
$ which composer
/usr/local/bin/composer
As you can see our hosting has an alias to ensure the configured version of php (for webserver) is used on command line. But composer is configured to use /usr/bin/php.
The following is a workaround for the above circumstance.
Update .bash_aliases file
alias php="/usr/bin/php7.2"
alias composer="/usr/bin/php7.2 /usr/local/bin/composer"
Once logged out of terminal and logged back in...
$ type -a composer
composer is aliased to '/usr/bin/php7.2 /usr/local/bin/composer'
composer is /usr/local/bin/composer
composer is now using the correct php version.

sudo update-alternatives --set php /usr/bin/php7.2
