Thank you for your interest in PHP.

Here's the "big" Code :

[Code]

if (@function_exists('bzcompress'))
{
$file_ext .= '.bz2'; $file_mime_type = 'application/x-bzip';
$file_contents = bzcompress($file_contents,9);
}
	else { $file_mime_type = 'application/x-csv'; }

[/Code]

This bug has been fixed in CVS. You can grab a snapshot of the
CVS version at http://snaps.php.net/. In case this was a documentation 
problem, the fix will show up soon at http://www.php.net/manual/.
In case this was a PHP.net website problem, the change will show
up on the PHP.net site and on the mirror sites.
Thank you for the report, and for helping us make PHP better.

Confirmed, 4.2.1 is broken. This bug is fixed in CVS, however.

is was using php4-win32-STABLE-200206110000.zip (and the "-latest" too !) snap for testing , and guess what -> this bug is still alive ! (how unexpected ... ;)

and you may ref. this a docu. bug, but even so i've tested against the newest docs. in the site and in the d/lable man.(s) - nothing has changed !

just marking the 4.3.0-dev too for carring this bug !

Give a small self-contained script which fails for you.

I wonder why it fails, it worked for me.

i could'nt supply the whole script as it relies on external classes - but i've verified this code to generate the "-8" too !

than Here you go :

<?php

$test_data = "ABCDEFGHIJKLMNOPQRSTUVWXYZ";

if (@function_exists('bzcompress'))
{
$test_data = bzcompress($test_data,9);
}
else { die(); }

// Send headers to the Browser (so it treats the output as a downloaded file)

ob_start(); // Output Buffering - Enables "Late" Header Transmission

header('Content-Type: application/x-bzip');

if ($_ENV["ETS_BROWSER_AGENT"] == 'IE') // IE need specific headers
{
        header('Content-Length: '.strlen($test_data));
        header('Content-Disposition: inline; filename="test_data.bz2"');
        header('Expires: 0');
        header('Cache-Control: must-revalidate, post-check=0, pre-check=0');
        header('Pragma: public');
}
else
{
        header('Content-Length: '.strlen($test_data));
        header('Content-Disposition: attachment; filename="test_data.bz2"');
        header('Expires: 0');
        header('Pragma: no-cache');
}

ob_end_clean(); // Output Buffering - End Cleanly

echo $test_data; // Output the File Contents Itself !

// File Download - Ends

?>

Confirmed, finally. ext/bz2 is broken in Release_TS, but works in Debug_TS.

Finally one takes a Full Checking upon this extension...

Setting to criticil. This may be related to streams, but not confirmed yet.

I've commited a fix no to CVS, but it needs some testing. Please wait a few hours from (don't know how long exactly) until the win32 snapshots are updated and try the latest then.

I wouldn't be surprised if you find some other problems with bz2 ...

Fixed ! :)
Finally... (the MySQL extension (?) of the 4.3.0-dev is bad or changed - but that's probably get a new report of itself anyway ;)
