ob_get_flush
> Dude, your web server will compute Content-length for you!
I've noticed that Apache 1.3 doesn't do that.
However, if you’re running Apache 2.2 (and maybe 2.0, haven't experienced that yet) you don't need to worry about Content-Length.
ob_get_length
(PHP 4 >= 4.0.2, PHP 5)
ob_get_length — Return the length of the output buffer
Beschreibung
int ob_get_length
( void
)
This will return the length of the contents in the output buffer.
Rückgabewerte
Returns the length of the output buffer contents or FALSE if no
buffering is active.
Beispiele
Beispiel #1 A simple ob_get_length() example
<?php
ob_start();
echo "Hello ";
$len1 = ob_get_length();
echo "World";
$len2 = ob_get_length();
ob_end_clean();
echo $len1 . ", ." . $len2;
?>
Das oben gezeigte Beispiel erzeugt folgende Ausgabe:
6, 11

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();
?>
