Code:
1. Eintragsdatei (Index .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';
Funktion 1. Legen Sie fest, ob es sich um den Debugging-Modus handelt (wenn APP_DEBUG im Debugging-Modus True ist, wird das zuletzt kompilierte nicht geladen ~runtime.php Im Bei der Entwicklung wird empfohlen, den Debugging-Modus zu starten)
2. Definieren Sie den Pfad von APP_PATH
3. Es ist auch der wichtigste Einstieg. Ab hier beginnt offiziell die komplexe, aber einfache TP-Framework-Reise Rahmen.
Ich werde dem TP-Quellcode folgen und vorstellen, wie die Seite aussieht, ohne Änderungen am TP vorzunehmen
( PS: Ich lerne das TP-Framework zum ersten Mal und habe auch gerade erst damit begonnen Ich hoffe, dass ich hier einige meiner eigenen Erfahrungen aufschreiben kann, um meine Gedanken zu ordnen. Wenn es Fehler gibt, hoffe ich, dass Sie sie darauf hinweisen können
Das Obige stellt den Ladevorgang von ThinkPHP32 vor (1), einschließlich verschiedener Aspekte. Ich hoffe, dass es für Freunde hilfreich ist, die sich für PHP-Tutorials interessieren.
