如何利用WebMan技術(shù)構(gòu)建強(qiáng)大的網(wǎng)站

CREATE TABLE users (   id INT AUTO_INCREMENT PRIMARY KEY,   username VARCHAR(50) NOT NULL,   password VARCHAR(255) NOT NULL );

<?php require_once 'webman.php';  webman()->route([   'GET /users' =&gt; function() {     $users = db()-&gt;select('users');     return JSon($users);   },      'POST /users' =&gt; function() {     $data = request()-&gt;post();     $user = db()-&gt;insert('users', $data);     return json($user);   },      'GET /users/{id}' =&gt; function($id) {     $user = db()-&gt;get('users', $id);     if (!$user) {       return text('User not found', 404);     }     return json($user);   } ]);  webman()-&gt;start();
