It is much clearer to break in/out of PHP "mode" than to have all
these echo statements.
?>
<div id="container">
<div class="head"><h2>Edit staff listing</h2></div>
<div><?php
if ($tstaffid < count($teachingstaff)) {
?>
<form action="tstaffsave.php" method="POST">
...
</form>
<?php
}
?>
</div>
</div>
This may or may not help with the newlines in your data...

You need to first be 100% sure that you don't have newlines in the
data itself.
If status should have no whitespace before/after it, you could also
just http://php.net/trim it for now, and figure out where the newline
is coming from later. But you'll want to track it down, as this will
likely not go away until you understand where it comes from.
