After installing lang/php4-4.3.8_1 + php4-zlib and setting 
"zlib.output_compression = On" in php.ini, all I get is garbage (looking 
like compressed data). Tried different browsers. 
I had to compile php with --with-zlib, and not with zlib as a loadable 
module to get it working correctly. 

Reproduce code:
any .php file

Expected result:
normal html code 

Actual result:
unreadable binary data.

I have the same problem. Zlib won't work when it's compilled as a module. Therefor I have to add it to the Makefile myself.

I'm running a FreeBSD I386 5.2-release with php 4.3.8

FreeBSD 5.3 BETA 6  AMD64(tried on 5.2.1 also); 
Apache/2.0.50 (FreeBSD) 
"zlib" is loaded as module.

Result (here phpinfo(); with zlib compression ON)
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 3.2//EN">

Confirmed on
Apache 2.0.52 (from ports, mod_deflate on by default)
PHP 4.3.9 (from ports, as an Apache module)
Zlib PHP module installed from /usr/ports/archivers/php4-zlib

With "zlib.output_compression = On" in /usr/local/etc/php.ini and "" in /usr/local/etc/php/extensions.ini,  the output looks like it is compressed, but there's no mention of compression in the HTTP headers. Disabling mod_deflate in the Apache config has not effect.

After changing zlib.output_compression to Off, the output is normal. Content is compressed if mod_deflate is on, uncompressed if off (as expected).

the same on FreeBSD 5.2, PHP Version 4.3.9 with zlib as dynamically loaded extension.
compiling zlib statically fixes the problem.
