Error 500: Premature end of script headers

Question

I get a \"Premature end of script headers: contactform.cgi\" error message when running the below script. What frustrates me is that I ran this as a .php on another server

Answer 1

After many diff's, this was what was missing from the httpd.conf file on the server in question:

AddHandler php5-script .php

Solved the issue.
