[SOLVED] Variables?

[phpcodec]

I have some variables like this:

 

$test1 = '1';

$test2 = '2';

$test3 = '3';

$test4 = '4';

 

and the url was http://www.somewebsites.com/index.php?word=test3

 

I tried:

 

$var = $_GET['word'];

echo $$var;

 

so in theory it should echo 3 or if the url was word=test2 it would echo 2

 

but it does not do this, how can i solve this?

try

<?php
$var = "test".$_GET['word'];
echo $$var;
?>

you still need to sanitize your input.

i'm sorry, but that does not work either

Does it echo nothing at all?  Are the variables being set on that page (stupid question, but people have come here over stupider things)?  Echo $_GET['word'] and make sure it's what you expect.

it echo's

 

$test2

oops. I wrote mine as follows

<?php
$test1 = '1';
$test2 = '2';
$test3 = '3';
$test4 = '4';
if (isset($_GET['word'])){
$var = "test".$_GET['word'];
echo $$var;
}

and i called it as such:

page.php?word=1
