global variables

8ride

My server admin says that he enabled global variables but they don't seem to work at all. Simple scripts that run on my one server will not run on this one. What is the exact setting he needs to change to enable them?

Right now I have to use:

 if ($_GET['Page']) {

instead of: (what I want)

 if ($Page) {

here are is the current PHP info

Hello again 🙂
Well, I prefer it when global variables are off, but anyhow.
There is one thing you can try to make your global variables on at all times, but depending on the server restrictions, it might not be possible.
However, give this a try:
In your root directory, or where ever you want to use your globals, put a file with the name .htaccess (it's a dot before the htaccess), and insert exactly this:
php_flag register_globals on

If you can logon to unix, you can also do this:
echo "php_flag register_globals on" > .htaccess

Make sure the file is world readable, 644 for example:
chmod 644 .htaccess

Then, if you're lucky, globals will be on.

Oh, and if your server is a Micro$oft sever, dohhhhh, I have no clue.

Yeah my server is a Microsoft server. So from that phpinfo.php link that I posted can you see if global variables are enabled?

Yeah,
just bring up the phpinfo page, and do a search for register_globals, you will see that they are turned off.

Hmm, too bad that it's not at least a Apache web server. I am not sure how you can turn the globals on by yourself. You should write the system admin and tell him to open the php.ini file. In there, he should change the line that says
register_globals off
to
register_globals on

Or, if the line does not exist at all, he should add it.

More I can't help for now :rolleyes:

Take a look at the discussions in the php manual. It's really not that hard to emulate having register_globals on. Basically just explode the $_GET array before doing anything else.

Of course, it's best to just use $GET and $POST.

What you can do is use the extract() function.

The only issue with that is people can pass off any variable in the URL and have it function as a normal variable in your script.
