Better yet, why not do some configuring in Apache. You could redirect the user to a diffent web page depending on the error message. Here are examples for error 404 and error 500, which are typical ones, that you could add to /etc/httpd/conf/httpd.conf configuration file or even to a .htaccess file.

ErrorDocument 404 /error_msgs/error_notfound.html
ErrorDocument 500 /error_msgs/error_scriptproblem.html
