Symfony process component points to wrong PHP version

Question

I am trying to run composer install with the Symfony process component like this:

if ($process->isSuccessful()) {
    $process = new Process("cd {$directory} && composer install");

    $process->run(function ($type, $buffer) {
        if (Process::ERR === $type) {
            Log::info($buffer);
        } else {
            Log::info($buffer);
        }
    });
}

It points to a PHP version of 5.6.25 which looks really strange because I am 100% certain I am using PHP 7. Running a phpinfo() inside Laravel gives me:

PHP Version 7.0.13

Running php -v from my terminal gives me:

PHP 7.0.13 (cli) (built: Nov 15 2016 23:52:36) ( NTS ) Copyright (c) 1997-2016 The PHP Group Zend Engine v3.0.0, Copyright (c) 1998-2016 Zend Technologies

This is the output that I am tailing from my log file which the Symfony process component is writing to:

Problem 1
    - Installation request for phpunit/php-code-coverage 5.0.0 -> satisfiable by phpunit/php-code-coverage[5.0.0].
    - phpunit/php-code-coverage 5.0.0 requires php ^7.0 -> your PHP version (5.6.25) does not satisfy that requirement.
  Problem 2
    - Installation request for phpunit/phpunit 6.0.6 -> satisfiable by phpunit/phpunit[6.0.6].
    - phpunit/phpunit 6.0.6 requires php ^7.0 -> your PHP version (5.6.25) does not satisfy that requirement.
  Problem 3
    - Installation request for phpunit/phpunit-mock-objects 4.0.0 -> satisfiable by phpunit/phpunit-mock-objects[4.0.0].
    - phpunit/phpunit-mock-objects 4.0.0 requires php ^7.0 -> your PHP version (5.6.25) does not satisfy that requirement.

Does anybody know why it points to a PHP version I am not using? I am running this on macOS by the way.

The strangest thing is that even if I use php -v in the Symfony process it shows that right version so it seems composer links to a wrong PHP version? I was able to install it locally though with composer by simply requiring it through my own terminal.

If anybody needs more information I am more than willing to try some things. Let me know.

Don't know for sure why this is happening, but you can skip platform requisites in composer with --ignore-platform-reqs option .

if ($process->isSuccessful()) {
    $process = new Process("cd {$directory} && composer install --ignore-platform-reqs");

    $process->run(function ($type, $buffer) {
        if (Process::ERR === $type) {
            Log::info($buffer);
        } else {
            Log::info($buffer);
        }
    });
}

This happened because the user that executes the symfony process component is different than my normal user which results in a totally different $PATH which does not have the usual globals that I had set.
