PHP 如何捕获 Catchable fatal error？

error_reporting(E_ALL);
ini_set("display_errors", "On");
function myErrorHandler($errno, $errstr, $errfile, $errline) {
  if (E_RECOVERABLE_ERROR === $errno) {
    throw new ErrorException($errstr, $errno, 0, $errfile, $errline);
  }
  return false;
}
set_error_handler('myErrorHandler');
for ($i = 0; $i < 5; $i++) {
    try {
        task($i);
    } catch (\Throwable $t) {
        echo " 执行失败，下一个\n";
        continue;
    }
}
function task($task_id)
{
    echo "执行任务 $task_id";
    if ($task_id == 2) {
        echo new stdClass();
    }
    echo " 成功\n";
}
