Retrieve Array From Cookie And Assign To Variables

[Brent Crouch]

Here is a piece of php code that I use on a smarty based website.  It works fine on that site.  I'm trying to modify it to work on a non-smarty site.

 

<?php

$_wc_ab = explode(",", $_COOKIE["_wc_ab"]);

if ($_COOKIE["_wc_ab"] == "") {

  $_wc_ab = array();

  for($i=1; $i<=20; $i++) {

    $_wc_ab[] = (rand(0,1) == 0) ? "A" : "B";

  }

  setcookie("_wc_ab",join(",",$_wc_ab),time()+(60*60*24*7),"/");

}

for($i=0; $i<count($_wc_ab); $i++)

  $smarty->assign("wc_cookie_" . ($i+1), $_wc_ab[$i]);

?>

 

 

Basically, when a visitor visits the site, the script checks to see if they already have a cookie named _wc_ab.  If not, it creates the cookie and assigns it a string of 20 randomly generated As and Bs separated by commas.

 

This portion of the script is working fine on my non-smarty based site.

 

I'm having trouble figuring out the syntax of retrieving the cookie array and splitting it into 20 separate variables named wc_cookie_1, wc_cookie_2, wc_cookie_3, etc  It obviously isn't

for($i=0; $i<count($_wc_ab); $i++)

  $smarty->assign("wc_cookie_" . ($i+1), $_wc_ab[$i]);

 

since this site doesn't use smarty.

Thanks for any help anyone can give.

<?php
$test = array('A','B','C');
for ($i=0;$i<count($test);$i++){
${"wc_cookie_" . ($i+1)} = $test[$i];
}
echo $wc_cookie_2;
?>
