Re: PHP processes

When PHP is compiled into Apache as a module, it runs as part of the Apache process. That means that each individual httpd process you see running on your system has an instance of PHP already running within it. If something, perhaps PHP, causes an Apache process to crash then only the request currently being served would be lost. The other Apache processes would still function normally and the master Apache process would launch a new process to replace the one that crashed. In this respect Apache+PHP is extremely robust. -Rasmus On Mon, 4 Dec 2000, Ashley T. Howes PhD wrote: > I just wanted to check a technical point with the list.
