$_GET question

[hostfreak]

I was wondering, on one of the hosting accounts I have, I have to use
[code]
$_GET['variable'];
[/code]

To retrieve something from the url parameters. Whilst on another hosting account I have, I don't have to use $_GET. Why is that?

you always need to define if the variable is coming from post or get or a cookie or a session or whatever. If you don't, php will accept it as a new variable which will cause a problem of values.

Maybe you don't need to write $_GET but $_HTTP_GET_VARS. That is because o different versions of php

The other host has a setting called register_globals enabled. You can still use $_GET['variable'] to access the variables from the URL if your other hosts is using a PHP version greater the PHP4.3.

indeed, but keep in mind that it is highly suggested [b]not[/b] to have register_globals enabled. you should always write your code in such a way as to work without it enabled since, as wildteen hinted at, as of PHP 4.3, it is disabled by default.

Makes sense now guys. Thanks. One host has php version 4.2 and the other had 4.4 . As you guys know (and I do now) the one with the 4.4 dindn't work. Well, I am off to recode it now.
