코드:

1. 항목 파일(색인) .php)

// 检测PHP环境
if(version_compare(PHP_VERSION,'5.3.0','<'))  die('require PHP > 5.3.0 !');

// 开启调试模式 建议开发阶段开启 部署阶段注释或者设为false
define('APP_DEBUG',True);

// 定义应用目录
define('APP_PATH','./Application/');

// 引入ThinkPHP入口文件
require './ThinkPHP/ThinkPHP.php';

기능 1. 디버깅 모드인지 여부를 설정합니다. (디버깅 모드에서 APP_DEBUG가 True이면 마지막으로 컴파일된 것이 로드되지 않습니다. ~runtime.php에서 개발의 경우 디버깅 모드로 시작하는 것을 권장합니다)

2. APP_PATH 경로를 정의합니다

3. 가장 중요한 것이기도 합니다. 이제부터 복잡하지만 간단한 TP 프레임워크 여정이 정식으로 시작됩니다. 좋은 장비가 없는 사람들도 장비를 가지고 가서 TP를 닦을 수 있습니다. 뼈대.

TP 소스 코드를 따라가며 TP를 전혀 수정하지 않고 페이지가 어떻게 나타나는지 소개하겠습니다

( PS: TP 프레임워크를 배우는 것은 이번이 처음이고 저도 이제 막 시작했습니다. PHP를 배우면서 제 생각을 정리하기 위해 여기에 제 경험을 적고 싶습니다. 혹시 잘못된 점이 있으면 지적해 주세요.

위 내용은 내용의 측면을 포함하여 ThinkPHP32 로딩 과정(1)을 소개하고 있으며, PHP 튜토리얼에 관심이 있는 친구들에게 도움이 되기를 바랍니다.
