UNDEFINED VARIABLE

[Anon]

I've often used variables defined in the end of the url to determine which files to include and what not.

For instance:
?id=3&sub=nerd

$id should be equal to "3", and $sub equal to "nerd", when used in the script.

I've never had a problem until I was setting up a local server on a computer at work. It's a windows 95 machine, I put apache 1.3.x and php 4.2 on it, along with the most recent mysql version. I did the default installation (as I've always done) and didn't edit any configurations besides httpd.conf to enable php in apache.

However, the script is not passing the variables, and I get an "undefined variable" error for $id. It's not reading them in the URL, somehow. Is this something I need to enable in a configuration file?

1. Make Error Reporting

error_reporting = E_ALL & ~E_NOTICE

2. Make Register Globals

register_globals = On

3. Learn how to script without either of the two above.

if (isset($GET[id])) {
echo($GET[sub]);
}

go with 3, as php reccomends using superglobals instead, or why else would they turn it off by default?

You could use a fuiunction like the following:

function arr_glob($ar, $arkey)
{
if (array_key_exists($arkey, $ar))
{return($ar[$arkey]);}
}

for example with a variable variable1

$variable1=arr_glob($_REQUEST, 'variable1')

so you don't have to use the $REQUEST['...'], $POST,... in the functions you write.

I found this very comfortable for porting code from 4.0.6 to 4.2
