阅读更多关于 Good Way to Email Exceptions

问题 I am running a site on Ubuntu with Apache and using PHP and Zend Framework. I would like exception information emailed to the devs and am wondering about a good way to do this. I don't want to email every single exception right away because if something major happens, our inboxes will get flooded.

问题 CUPS implements its own web server to host CGI programs on http://localhost:631 server: https://github.com/apple/cups/blob/master/cups/http.c CGI pages: https://github.com/apple/cups/tree/master/cgi-bin Creating a web server just for a printing daemon seems like duplicate code and bloat that might lead to code harder to maintain and possible creation of bugs. Why an actual httpd daemon like Apache is not used? 回答1: CUPS uses the Internet Printing Protocol (IPP) for transferring jobs from

问题 I am moving from a server with PHP 5 to a new server with PHP 7, and I am having issues to tell Apache to parse .html as PHP scripts.
