PHP 4.1.1 binaries (and earlier versions) using Apache 1.3.23 in Windows XP Prof. corrupts HTML output with random binary code to clients connecting from remote computers. Output in localhost is fine. This seems to happen if the HTML is lengthy. The problem can be solved turning implicit_flush from php.ini to on, but this is a rather poor solution as it degrades performance quite a lot. Below is an example of corrupted output, both from same source.

Yes - I'm getting that bug.
It seems that things are fine when databases are not used, but when mysql is used repeatedly on a page this happens.

Look at this phpBB output:

I seem to be getting $I30 repeated.
 [2002-02-06 21:57 UTC] yohgaki@php.net
I found why you get corrupted output w/o ob_implicit_flush.
PHP was removing the last buffer enabled, I fixed this.
Therefore, real problem should be the last buffer you've enabled.

Could you locate the last buffer?
If it's a you buffer wrtten in PHP, I need only the output handler function.

I also need following php.ini entry settings

output_buffering
output_handler
zlib.output_compression
implicit_flush

I'm also experienceing this bug on Linux 2.4.4, running Apache 1.2.23 and PHP 4.1.1.  It also only appears on lengthy pages, but on one short one also.  In VIM, it shows up as a stream of characters looking like this:

^@^@^@^@^@... and so on.

Just confirming that this isn't limited to WindowsXP.
 [2002-03-20 14:57 UTC] wez@php.net
See also Bug #15613, which seems almost the same but
implicit_flush doesn't make a difference.
 [2002-04-24 19:33 UTC] yohgaki@php.net
Could you try 4.2.0 and report the result back?
