你 $this->display(); 没有参数，通常就会使用与方法名相符的模板，即 view/modify_photo.html
如果你需要使用其他模板，则需要自行指定
$this->display();里面应该有参数的，是你想要指定模板的路径，默认的应该是当前方法名的模板
如果为空代表是当前方法名的模板，如果要指定其他控制器的其他方法名的模板。 $this->display('控制器名:方法名');
如果为空代表是当前方法名的模板，如果要指定其他控制器的其他方法名的模板。 $this->display('控制器名:方法名');

How do you loop through all the values stored in a PHP session?Apr 26, 2025 am 12:06 AMIn PHP, iterating through session data can be achieved through the following steps: 1. Start the session using session_start(). 2. Iterate through foreach loop through all key-value pairs in the $_SESSION array. 3. When processing complex data structures, use is_array() or is_object() functions and use print_r() to output detailed information. 4. When optimizing traversal, paging can be used to avoid processing large amounts of data at one time. This will help you manage and use PHP session data more efficiently in your actual project.
