Is PHP exit status only useful when launched from the command line?

Question

I was just reading the documentation for PHPexit .

It says that you can pass an integer (0-254), which will become the exit code ...

exit(5);

Is this only useful when working with PHP under the CLI? Can Apache use the error code for anything? Will PHP working normally always use exit code 0?

thank
