How does a PHP website prevent important server information from being displayed when the file behind the website does not exist?

When a PHP website does not display important server information such as & nbsp; http: // & nbsp; url & nbsp;/abc. asp & nbsp; If this file does not exist, the error page shown in figure (image 1) is displayed. However, the error information may leak server-related information, how can I prevent him from displaying this interface, or, when an error occurs, when the PHP website directly causes the file after the website to not exist, it will not display important server information
For example, http: // URL/abc. asp. If this file does not exist,
The error page shown in Figure 1 is displayed ),

However, an error message may expose server-related information. how can I prevent this interface from appearing? or, when an error occurs, a prompt is displayed (image 2)

Apache ErrorDocument 404/404 .php in the configuration file
