It's possible to select a PHP version greater than the one the project is constructed on

[raphaelstolt]

This leads to problems (like shown in the following console excerpt) when doing the composer install.

Creating your project...
Loading composer repositories with package information
Installing dependencies (including require-dev)
Your requirements could not be resolved to an installable set of packages.

  Problem 1
    - This package requires php >=5.6.0 but your PHP version (5.5.9) does not satisfy that requirement.

Perhaps instead of using 5.6.0 by default, construct should use the php version that it's installed when the command is executed.

[raphaelstolt]

Yes the default PHP version should be the one used on the constructing system, and it shouldn't be possible to choose one greater than it.

[jonathantorres]

Agreed.
