<p>如何在單一安裝的 Codeigniter 4 中從其他多應用程式網站呼叫模型？ </p> <p>資料夾結構如下：</p> <pre class="brush:php;toolbar:false;">- WebsiteFolder -- Site1 --- app --- public --- tests --- writeable (.env, spark and other file) -- Site2 --- app --- public --- tests --- writeable (.env, spark and other file) -- system</pre> <p>這是我的範例程式碼：</p> <p><strong>在站 1</strong></p> <hr /> <p><strong>Constants.php</strong> 我已經定義了一個根目錄來定位 site2。 </p> <pre class="brush:php;toolbar:false;">define('ROOTSOURCE', dirname(__DIR__,3) .

// Create a new class manually
$userModel = new \App\Models\UserModel();

// Create a new class with the model function
$userModel = model('App\Models\UserModel', false);

// Create a shared instance of the model
$userModel = model('App\Models\UserModel');
