Hi...
I'm getting to grips with custom error handling, and am wondering if it is
possible to somehow reset all the content already sent to the browser, and
send some new stuff in its place.
For example, if I'm looping through a database, and I've already written 10
records to the browser, and then an error occurs, is it possible to send a
command to the browser that makes it drop everything it's received thus far,
and then just have it print the output of my custom error handling function
instead? I'm guessing not, because I think only headers can do such things,
and they've already been sent, but it's worth asking!

Turn output buffering on. All output goes in the buffer and is output
when your script terminates. You can clear it if you wish before then.
It can hog memory on the server though if there's a lot of output. http://uk.php.net/manual/en/function.ob-start.php

Not quite "resetting" the browser, but an option:
You may want to try somesort of javascript function.
<?
$error_page = "http://blah.com/error.php";
if($error)
{
print "<script language='JavaS cript' type='text/JavaScript'>";
print "<!--\n";
print "window.locatio n =\"$error_page\ "";
print "//--></script>";
}
?>

Your idea of how PHP (or any other language for that matter)
constructs HTML pages and sends them to the client's browser is
entirely wrong. Your PHP script may construct the web page in stages,
but it is only when it is complete that it is sent to the browser.
Just because your code has finished constructing a bit of HTML does
NOT mean that it is already being displayed on the client's device.
You do NOT write directly to the browser, you write to an output file.
It is only when the file is closed that it is sent to the browser.

If an <IMG> specifies a WIDTH but not a HEIGHT, then height is internally
determined so as to maintain the image's aspect ratio.
Aspect ratio is also preserved if HEIGHT but not WIDTH is specified.
What is the value of an unspecified HEIGHT or WIDTH attribute. How do I
dynamically set the attribute to unspecified, after having previously used
the <IMG> with explicit HEIGHT and WIDTH attributes?

This seems to be related to the ViewState error that is now starting to
plague ASP.Net apps. When the Application Pool is recycled, the Session
seems to be getting reset. When this is done, session information is
lost and my app forgets what rules a user has. I'd rather not recode to
read this from the database for every page, but I wonder if I have no
other choice. Anyone else notice the Session resetting?
