how to start php from html file using operating_system_level_command <!--exec in otherwords, what is php's "standalone" name (don't know how to express it correctly)
You can't just call php from the command line. In order to do that, you must compile PHP into CGI-mode which will give you a binary that you can use (like perl) to run scripts.
Thank you very much for your answer. Have you been able to succesfully do that in Unix? My initial problem is that I would have to "call" php from html file (without changing the .html to .php) and even send parameters to the script. Would you're advice solve the problem? And where could I find more info?
If you look in these forums you'll find that there have been other people who want to include PHP in html. They have found several way's of doing it.
Do a search and you'll find it.
