RE: [PHP] next,key,current question
Sara,
Try this: $count = count ($Classes); for($i=0; $i<$count; $i++){ $CurrentIndexValue = key($Classes); $CurrentContents = current($Classes); echo "<option value='$CurrentIndexValue'>$CurrentContents</option>"; next($Classes); } instead of the for loop you're using. currently you're doing a next first, which will move you to the next element in the array. And then you're echoing the variables from the while loop, you should be using the variables you've got in the for loop. chris -----Original Message----- From: Sara Daugherty [mailto:sara@areawebdirectory.net] Sent: Thursday, November 13, 2003 3:02 PM To: php-general@lists.php.net Subject: [php] next,key,current question I am having trouble with creating a list box.
