Hello,
I have just upgraded to PHP 4.2.0 and straight away one of our custom PHP
extenstions reported an error (couldn't get SCRIPT_NAME):
Scripthash Security Extension - http://www.scl.co.uk/scripthash/
The reason for this seems to be that a global variable I need SCRIPT_NAME has
been moved into the $_SERVER superglobal. As a quick, temporary fix I enabled
register_globals in the .ini file, this worked fine. My next task was to find
out how I should really do this so I had a look through some of the provided
PHP extenstions and I noticed that session.c (and several other modules) was
using the same method to fetch HTTP_REFERER and REQUEST_URI as I was using to
fetch SCRIPT_NAME which is using the zend_hash_find() function.
Does this mean that in order for the session extension to work properly
register_globals has to be enabled or have I overlooked something. What method
should I now be using to fetch variables inside the superglobals from with in
my extension source code. I know I could use getenv() for this particular
example but what is the alternative.
Thank for you time
Tom.
