There is a work-around for the situation you need to get length of the gz-ed buffer.



ob_start();

ob_start('ob_gzhandler');



  ... output the page content...



ob_end_flush();  // The ob_gzhandler one



header('Content-Length: '.ob_get_length());



ob_end_flush();  // The main one

It's interesting how ob_start("ob_gzhandler"); or ob_gzhandler(); affect this function. The returned size is the buffer uncompressed size; therefore something like strlen(ob_get_contents()); just (hopefully) faster. However in order to obtain the compressed buffer size; there seem to be no function around.

Here is an easy way to get the header Content-Lenght.


<?


ob_start();


?>





Put HTML tags.





<?


$size=ob_get_length();


header("Content-Length: $size");


ob_end_flush();


?>
