How to end loop when desired value is found.

Question

Hi I have a loop below and I want the loop to end when the desired value is found.
<?php do { ?>
<?php $allvotedid = $row_VotedUsers['VotedID'] ?>
<?php } while ($row_VotedUsers = mysql_fetch_assoc($VotedUsers)); ?>
I want this loop to end when $row_VotedUsers['VotedID'] equals the URL variable ID. So lets say pagename.php?ID=1, I want the loop to go until it finds a value equal to ID which is 1. And then I want it to assign that value to $allvotedid. And if finds no value equal to it then I want it to stop looping.
Thanks for any help. I hope I made this clear.

The following will do what you have asked for:
<?php do { ?>
<?php
if (isset($_GET['ID']) && $_GET['ID'] == $row_VotedUsers['VotedID']) {
  $allvotedid = $row_VotedUsers['VotedID'];
  break;
} ?>
<?php } while ($row_VotedUsers = mysql_fetch_assoc($VotedUsers)); ?>
However, it's a very inefficient way of doing it. If what you're interested in is whether the ID passed through the URL is in the VotedID column, just create a recordset using the URL parameter ID ($_GET['ID']) as the filter. Then check the value of $totalRows_VotedUsers. If it's 1, the user has voted. If it's 0, the user hasn't voted.
