If you are trying to insert a pagebreak every 50 lines, that's not too hard to do in perl:
(Untested)
You'll need to put an actual page break in there where it has ^L (ie don't copy-paste the ^ and the L characters, use a single control-L character).

This means that at the top of the search results like "Today's Post" and "New Posts" and keyword searches, the stats will appear at the top of that page instead of the home page.

headers_sent
HEADERS_SENT(3) 1 HEADERS_SENT(3)headers_sent - Checks if or where headers have been sentSYNOPSIS
bool headers_sent ([string &$file], [int &$line])
DESCRIPTION
Checks if or where headers have been sent.
You can't add any more header lines using the header(3) function once the header block has already been sent. Using this function you can
at least prevent getting HTTP header related error messages. Another option is to use Output Buffering.
PARAMETERS
o $file
- If the optional $file and $line parameters are set, headers_sent(3) will put the PHP source file name and line number where out-
put started in the $file and $line variables.
o $line
- The line number where the output started.
RETURN VALUES headers_sent(3) will return FALSE if no HTTP headers have already been sent or TRUE otherwise.
EXAMPLES
Example #1
Examples using headers_sent(3)
<?php
// If no headers are sent, send one
if (!headers_sent()) {
header('Location: http://www.example.com/');
exit;
}
// An example using the optional file and line parameters, as of PHP 4.3.0
// Note that $filename and $linenum are passed in for later use.
// Do not assign them values beforehand.
if (!headers_sent($filename, $linenum)) {
header('Location: http://www.example.com/');
exit;
// You would most likely trigger an error here.
} else {
echo "Headers already sent in $filename on line $linenum
" .
"Cannot redirect, for now please click this <a " .
"href="http://www.example.com">link</a> instead
";
exit;
}
?>
NOTES
Note
Headers will only be accessible and output when a SAPI that supports them is in use.
SEE ALSO ob_start(3), trigger_error(3), headers_list(3), header(3) for a more detailed discussion of the matters involved. .
