ThinkPHP — Lightweight Rapid Development PHP Framework

Introduction

ThinkPHP is a PHP framework with over two decades of development history, designed for fast web application development with a low learning curve. It follows convention-over-configuration principles and provides a complete toolkit for building web applications and APIs.

What ThinkPHP Does

• Provides an MVC architecture with automatic routing and URL rewriting
• Includes an ORM with query builder and model relationships
• Offers built-in template engine with tag library support
• Supports middleware, events, and service providers
• Provides CLI tools for code generation and task scheduling

Architecture Overview

ThinkPHP uses a multi-application architecture where a single installation can host multiple independent applications. The request lifecycle flows through middleware stacks, route matching, controller dispatch, and response rendering. The framework supports both traditional request-response and command-line application modes, with a service container managing dependency injection.
