1. 学生类Student

   <?php
   
   class Student
   {
      public $name;
      public $age;
      public $sex;
      public function __construct($name,$age,$sex)
      {
          $this->name = $name;

3. 类的自动加载文件

   <?php
   //类的自动加载器:最重要的一个参数就是一个回调
   spl_autoload_register(function($className){
     require __DIR__ . '\public\\' . $className . '.php';
   });
   $student = new Student('李明',12,'男');
   $teacher = new Teacher('朱老师',30,'男');
   echo '学生:' . $student->name . '的年龄是: ' . $student->age . ',性别是: ' . $student->sex . '<br>';
   echo '老师:' . $teacher->name . '的年龄是: ' . $teacher->age . ',性别是: ' . $teacher->sex . '<br>';
