Installing and Configuring ThinkPHP 6.0 with Multi‑Application Support

ThinkPHP has evolved to version 6.x, which introduces a streamlined core and unified usage while requiring PHP 7.1+; it does not support seamless upgrades from 5.1.

Since the official site no longer provides direct downloads, the framework must be installed or updated via Composer. composer create-project topthink/think thinkphpV6.0.5 The default installation creates a single‑application directory structure. For multi‑application projects you need the think-multi-app extension. composer require topthink/think-multi-app Be sure to run the Composer command in the project root; otherwise the extension will not be usable and you may encounter missing controller errors.

Delete the existing app/controller directory and generate a new module (e.g., index) with:

php think build index // index is the module name

// To create an admin module, replace "index" with "admin".

After running the command, the new module appears in the project tree (visible in IDEs such as PhpStorm).

Three core files— BaseController.php, Request.php, and ExceptionHandle.php —can be moved freely, but their namespaces must be updated accordingly, and any changes to class names must be reflected in provider.php.

Install the view engine driver: composer require topthink/think-view Now the application can be accessed via a browser, for example: http://localhost:8010/thinkPHPV6.0.5/public/ (adjust the port as needed).

If you encounter the error "No input file specified.", edit the .htaccess file in the public directory, changing: RewriteRule ^(.*)$ index.php/$1 [QSA,PT,L] to RewriteRule ^(.*)$ index.php [L,E=PATH_INFO:$1] After correcting the rewrite rule, the application should load correctly.
