globals??

[svenski]

Transferring my site from a Wintel IIS box to a Linux Apache box and now every reference i make to a variable name contained in an URL is broken, ie if the url = page.php?var=3

echo $var;

produces nothing. Whats happening?
TIA

try:

echo $_GET['var'];

ok, this works thanks, but i'd rather not go through and change all my scripting, is there another work around to do with server settings

Thanks for the help.......

function reg_globals() {
    foreach($_GET as $curVar) {
        global $$curVar;
        $$curVar = $_GET[$curVar];
    } //end foreach
    foreach($_POST as $curVar) {
        global $$curVar;
        $$curVar = $_POST[$curVar];
    } //end foreach
} //end reg_globals

Why not just use import_request_variables??

http://us2.php.net/manual/en/function.import-request-variables.php

import_request_variables("gp");

also, your functions foreach statements don't look right to me.

foreach($_GET as $curVar){

will give you the values of the items in the get array, not the keys.
if you passed in foo=bar your function will create $bar = 'bar'.
you need to use

foreach($_GET as $curKey => $curVar){
        global $$curKey;
        $$curKey = $curVar;
}

odd, because it doesn't work for me.
here is reg_globals.php

<?php

reg_globals();

print "$foo<br>\n";
print "$foo2<br>\n";

function reg_globals() {
    foreach($_GET as $curVar) {
        print "curVar = $curVar<br>\n";
        print "_GET[$curVar] = {$_GET[$curVar]}<br>\n";
        global $$curVar;
        $$curVar = $_GET[$curVar];
    } //end foreach
    foreach($_POST as $curVar) {
        global $$curVar;
        $$curVar = $_POST[$curVar];
    } //end foreach
} //end reg_globals
?>

when I go to that script passing variables to it:
reg_globals.php?foo=bar&foo2=5

it does not create the variables $foo and $foo2 and the variable $bar is empty. Here's the output of the print statements in that foreach loop:

curVar = bar
GET[bar] =
curVar = 5
GET[5] =

can you show me an example of a script using that function that works.

Or you can do this the newbie way using extract($_GET); 😃
