Shortening variable strings

[Jon12345]

Is there a shorter way of doing this?

<?php
$t=$_GET['t']; 
$t=$_GET['o']; 
$site="http://abc.com?sub=t-".$t."&o=".$o;
header("location: ".$site);
?>

i.e. can I just use this instead?

<?php
$t=$_GET['t']; 
$t=$_GET['o']; 
$site="http://abc.com?sub=t-$t&o=$o";
header("location: ".$site);
?>

Thanks,

Jon

Looks like it should work, other than the fact that I think you wanted the second variable assignment to be for $o (instead of $t again).

However, I would suggest filtering/validating those input values in order to avoid undesired effects from invalid $GET values. At the very least they probably should be [man]urlencode/man'ed, or if they are integers they could be cast to such.

// let's assume the first is a string and the second an integer:
$site = sprintf("http://abc.com?sub=t-%s&o=%d", urlencode($_GET['t']), (int)$_GET['o']);
header("Location: $site");
