curl - Run composer with a PHP script in browser

Question

Wondering if it's possible to execute composer from the browser with a little PHP wrapper as I don't have access to shell access to the server.

Not sure if you can do this with cURL?

Answer 1

An alternative to Danack's solution, is to include "composer/composer" as a dependency in your composer.json, and just use it's API, instead of extracting the contents from composer.phar.

composer.json

...
"require-dev": {
  "composer/composer": "dev-master",
}
...

Run composer install manually, so you'll be able to require it on the following script:

composer_install.php

<?php
require 'vendor/autoload.php'; // require composer dependencies

use ComposerConsoleApplication;
use SymfonyComponentConsoleInputArrayInput;

// ComposerFactory::getHomeDir() method 
// needs COMPOSER_HOME environment variable set
putenv('COMPOSER_HOME=' . __DIR__ . '/vendor/bin/composer');

// call `composer install` command programmatically
$input = new ArrayInput(array('command' => 'install'));
$application = new Application();
$application->setAutoExit(false); // prevent `$application->run` method from exitting the script
$application->run($input);

echo "Done.";

When you access the script from your browser, the command should run as expected.
