Re: How to get script filename in module RINIT function

I don't think I made myself exactly clear. There are 2 use cases I would like to consider: 1. CLI: by using "php /full/path/to/script.php" or "cd /full/path/to && php script.php" 2. Apache DSO: going to http://www.domain.com/script.php which in turn 'executes' script "/full/path/to/script.php" In both cases, in RINIT I would like to get full path (real path, if possible) of this /full/path/to/script.php. Is this possible or is your way the only viable solution (with performance penalty etc)? (The $_SERVER['SCRIPT_FILENAME'] was just a method to explain what I would like to have, albeit obviously a poor one:) Thanks again, b. 2010/8/9 Johannes Schlüter <johannes@php.net> > On Mon, 2010-08-09 at 13:32 +0200, Bostjan Skufca wrote: > > Hi all! > > > > I am developing a small PHP extension and I ATM can't figure out how to > get > > to $_SERVER['SCRIPT_FILENAME'] content while in PHP_RINIT or > PHP_RSHUTDOWN > > function.
