I have used:
ini_set('display_errors', '1');
ini_set('display_startup_errors', '1');
error_reporting(E_ALL);
at the beginning of my code. However, the error messages are displayed directly in the output (there are a lot of them, so you can't find the errors very well).
After the script is loaded, how to display all errors that occurred?

You can use error/exception handlers with destructors. The handler catches the error and the destructor will display the caught error at the very bottom of the page.
class ErrorHandler { private static $instance = null; private static $errors = []; public static function Init() { if(!self::$instance) { self::$instance = new self; set_error_handler(function($errno, $errstr, $errfile, $errline){ self::$errors[] = new ErrorException($errstr, 0, $errno, $errfile, $errline); }); set_exception_handler(function($ex){ self::$errors[] = $ex; }); } } function __destruct(){ foreach(self::$errors as $errstr) echo $errstr, ''; } } ErrorHandler::Init();
