Problems with variables

[rulian]

For some reason my php doest want to read variables passed through get, for example the following code:

<?php

echo $hey;

?>

use to work if my url read test.php?hey=hi

however, on my website no variables can be read using the page.php?variable=value system

or am I doing something wrong?

try using this:

<?php

echo $_GET["hey"];

?>

PHP has changed somewhat and now register_globals defaults to off, use the associated superglobal ($GET,$POST,$SESSION,$COOKIE,$ENV,$SERVER)...

wow, good to know, but just to clear something up, so now if I want to use a session variable or a cookie variable I cant just call them anymore, i gotta go $variable=$SESSION["variable"]; and $cookie=$COOKIE["cookie"]; ?

thanks though, that worked splendid

Prety much. Unless a) you or your host enables register_globals in the php.ini or b) you use a function called var_dump() i think which will dump (pun intended) the variables into the global scope. Although the latter is not recommended as it could and will if overwrite variables if they already exist...
