Subject: [PHP] Urgent help - Token Generation code!

I am re-visiting the world of PHP after a really big hiatus and I
am finding
things veryslippery. Can someone please help me with the below code
and let
me know how I can print the token that is getting generated?

I am using EasyPHP and I am trying to echo the $token but it
wouldn't print
anything. I am trying it as : http://localhost/token/URLToken.php.
May I
know where all I am going wrong here in my approach?




$sUrl = "/tstd_c_b1@s54782";
$sParam = "primaryToken";
$nTime = time();
$nEventDuration = 86400;
$nWindow = $nTime + $nEventDuration;
$sSalt = "akamai123!";
$sExtract = ""; // optional



As a second try, what happens if you add right here the line

$sGen = urlauth_gen_url($sUrl, $sParam, $nWindow, $sSalt, $sExtract,  
$nTime);


Because it seems as though you just declare three functions in the  
code

without calling them...



function urlauth_gen_url($sUrl, $sParam, $nWindow,
$sSalt, $sExtract, $nTime) {



$sToken = urlauth_gen_token($sUrl, $nWindow, $sSalt,
$sExtract, $nTime);
echo $token;


There are two cases:
1. You made a typo and meant 'echo $sToken;' on the above line  
instead

2. You omitted the part where $token is defined and used


[More code that seemed fine]

I forgot to hit Reply All instead of Reply.
I am deeply sorry for such a careless omission.
