RE: [PHP] NULL Apache environment variables
-Original Message- From: Erik Price [mailto:[EMAIL PROTECTED]] Sent: Monday, February 18, 2002 5:58 PM To: Lars Torben Wilson Hm? I didn't think that this was the case -- I thought that although there is a long-term move to making 'register_globals = off' default, register_globals is still default to be 'on'. I think that this is described in the 4.1.0 release announcement. Indeed, the 4.1.0 release notes say this: PHP 4.1.0 still defaults to have register_globals set to on. [...] As of the next semi-major version of PHP, new installations of PHP will default to having register_globals set to off. No worries! Existing installations, which already have a php.ini file that has register_globals set to on, will not be affected. ... and the 4.1.1 release notes do not contradict this. I took next semi-major version to mean 4.2.0, but if this change has actually occurred in 4.1.1 this should be made clear, both in the release notes and the manual section on Configuration. Perhaps it would have been better to state an actual version number, rather than an opaque phrase like next semi-major version. Cheers!

Re: [PHP] NULL Apache environment variables
Have a look at the function getenv().. eg: $ip = getenv (REMOTE_ADDR); // get the ip number of the user HTH Neil Narvaez, Teresa wrote: Hello, I'm running PHP version 4.1.1.

Is there a missing configuration on apache or php?

RE: [PHP] NULL Apache environment variables
Thank you ... that worked! I did not know this because I looked at a sample in www.php.net and the sample fails to call getenv().

RE: [PHP] NULL Apache environment variables
The function call phpinfo() shows register_globals=off for master and local value on my system. I installed PHP and did not change anything because I do not know enough to make changes so I believe off is the default value.

Did you install someone else's pre-compiled binary? I know that my 4.1.0 source install ended up with register_globals = on by default, and I had to manually change this to off. But that was over a month ago. There are others on this list more knowledgeable than I about the default setup of the php.ini file. In any event Teresa, you are much better off learning PHP with register_globals = off because it will get you used to using $_* arrays, as the old globalized means of accessing variables has been deprecated.

RE: [PHP] NULL Apache environment variables
Erik, Thanks for your response. No I did not install a pre-compiled binary. I got the tar ball and compiled it myself. By the way, I am running PHP version 4.1.1.
