ThinkPHP Framework Execution Process Overview

ThinkPHP framework execution process

The overall flow can be summarized as: index.php → load framework → read configuration → generate application → load classes → instantiate classes and invoke methods → template rendering (display).

<code>--&gt; index.php (entry, debug mode, application path)
--&gt; ThinkPHP.php (define paths and access mode)
--&gt; Think\Think (class loader, exception handling, read common config)
--&gt; Think\App (request URL dispatch parsing, execute dispatch result)
--&gt; exec (execute user-defined Controller's Action method)
--&gt; Think\Dispatcher (parse M, C, A and parameters from URL, load module config)
--&gt; Think\Controller (call view, wrap and redirect)</code>

The internal process is relatively simple, with two important additional classes:

Think\Hook: listens to App, Action, View stages and executes Behaviors.

Think\Behavior: configurable via configuration files and can be added or removed in code.
