One way, as you just have ruled out, would be using the ob_ functions.
However you can redirect the browser using JavaScript, with the drawback
that this will only work with compliant clients and JS not disabled.
Passing data to the error page could be done by using session data, or if
you don't want to use sessions, create a temp file and pass the name and
location to the error page.
Sending the javascript:
<?php
if ($we_found_an_error) {
$url = 'http://' . $_SERVER['SERVER_NAME'] .
'/my_error_handler.php?any_parameters_you_need';
echo '<script language="JavaScript">',
'document.location.href="', $url, '">',
'</script>',
'<hr>',
'A nasty error has occurred. If you are not redirected ',
'to the correct page, <a href="',$url,'">click here</a> to',
'continue (sorry folks)';
}
// else no error - continue
?>
Hope this helps,
