Question

I have the following code with the if…else statement within a while loop.

$colour = array("50305A", "E33600", "DBDD02", "73BE58");
$nextcolr = next($colour);
 if ($nextcolr == FALSE)
 {
    reset($colour);
    echo current($colour);
 }
 else
 {
    echo next($colour);
 }

I can’t work out why what ever is in the else statement isn’t being executed, even if I switch the two statements and reverse the operator. Could anyone help me?

The entire while loop:

while($row = mysql_fetch_array($result))
  {
  echo "by <a href='/neuro/profile.php?userid=$row[MemberID]'>" . $row['FirstName'] . " " . $row['LastName'] . "</a> on " . $row['Timestamp'] . " | " . $row['NumberOfComments'] . " comments.";
  echo "<div id='blog' style='background-color:#";
  if ($nextcolr == FALSE)
    {
    reset($colour);
    echo current($colour);
    }
  else
    {
    echo next($colour);
    }
  echo "'><a href='blog.php?threadid=" . $row['tID'] . "'>" . $row['Title'] . "</a></div>";
  }

Answer 1

$colour = array("50305A", "E33600", "DBDD02", "73BE58");
while ... {
    $nextcolr = next($colour);
    if ($nextcolr === FALSE)
    {
        reset($colour);
    }
    echo current($colour);
}

is how your while loop should look like. If I am right, you are also defining $colour in the while loop, which might cause problems.
