I've released php-activate 0.1.2, a PHP project version manager for Linux systems using native PHP packages.

Made for those working with multiple projects using a variety of PHP versions, this script will automatically switch to the correct PHP version after cding into the project folder. It does not require sudo, so even works in IDEs.

The latest version contains only documentation changes, but I've been using this successfully for a few months, so wanted to share this more widely. #projects #phpactivate

Basic routing using REQUEST_URI

So for nginx it is not straightforward to setup PHP-FPM so that PATH_INFO is correctly populated. Lamb uses the following /index.php/some/other type routing, where /some/other should be the PATH_INFO. Instead I want to make setup for a variety of web-servers straightforward, so I've switched to the more robust REQUEST_URI. This simplifies nginx configuration and Caddy and the PHP built-in web-server are compatible.

REQUEST_URI contains everything after the domain name, including the query string, so that needs to be removed:

$request_uri = '/home';
if ( $_SERVER['REQUEST_URI'] !== '/' ) {
    $request_uri = strtok( $_SERVER['REQUEST_URI'], '?' );
}

We can see that for a request for the root of the site, REQUEST_URI returns / whereas PATH_INFO would be empty, so the code above takes that into account. We can then deduct a router action as follows:

$action = strtok( $request_uri, '/' );

Once the $action is known, it can be checked against an allowed list of actions:

switch ( $action ) {
    case 'edit':
        ...
        break;
    default:
        respond_404();
        break;
