Placeholder: How should this buildpack request a PHP version?

[joshuatcasey]

Should it use any or all of the following?

1. composer.lock "platform.php-64bit"
2. composer.lock "platform.php" (this is 32-bit)
3. composer.json "require.php-64bit"
4. composer.json "require.php" (this is 32-bit)
5. BP_PHP_VERSION?
