推荐答案

使用PHP不可能做到这一点，因为PHP在服务器上执行，并且必须按照定义在客户端上截屏.您可以使用客户端技术(例如 html2canvas 库)在客户端截屏.然后，您可以根据需要将屏幕截图发送到服务器端PHP代码.

This is not possible using PHP, as PHP executes on the server and a screenshot by definition must be done on the client. You could take a screenshot on the client side using client-side technology like the html2canvas library. Then you could send the screenshot to your server side PHP code if you wanted to.
