composer_manager + PHP 8.2 issues

I think it's time to ignore the README in this module, and ignore composer_manager.

I'm not super experienced with Drupal 7 + composer / have only used composer_manager once, years ago... but just tried following the installation instructions, and something is completely unusable. Probably some bridge code between composer(manager) + drush, probably because it doesn't work with PHP8.2.

I believe most people who use composer libraries with Drupal 7, install/update them manually, independently of Drupal (just using composer), and then add just one line to the index.php:

/**
 * Root directory of Drupal installation.
 */
define('DRUPAL_ROOT', getcwd());

require_once DRUPAL_ROOT . '/../vendor/autoload.php'; /////// <- this one

require_once DRUPAL_ROOT . '/includes/bootstrap.inc';
drupal_bootstrap(DRUPAL_BOOTSTRAP_FULL);
menu_execute_active_handler();

The above example is when you ran composer require onelogin/php-saml:~3 outside of the public HTML directory, i.e. your vendor/ is at the same level of your 'web/' directory. It is possible, though a little less recommended, to put vendor/ inside the "web" directory - then remove a "../" from the path.

Feel free to post updates. I still have a soft spot for D7, though I hardly maintained the D7 module. (Only released a new version in 2021/2022 after the original maintainer had left.) I see the 7.x-1.x-dev version contains a fix and two extra features that I never tagged a release for, and there are two extra features (tagged needs work) still in the queue → .

For completeness: this means there's no need to install composer_manager (and/or whatever other stuff that 'drush composer-manager' tries to download).

And I see the composer.json from the D7 version requires / has only been tested with onelogin/php-saml version ~3 whereas you probably need version ~4 (or ^4, no practical difference).

I do not expect any compatibility issues between those versions.

Thanks @roderik. Actually I did finally arrive at your suggestions, and I updated the composer.json file to use version 4. Now it's recognizing that the library is there, all I need to do is configure the module settings with my certs, etc.
