'ob_gzhandler' conflicts with 'zlib output compression'

[Ronald Wiplinger]

I have upgraded to Apache 2.0.45 and PHP-4.3.2RC2 and find now many lines in the apache log files:

[client 192.168.250.117] PHP Warning: ob_start(): output handler 'ob_gzhandler' conflicts with 'zlib output compression' in /usr/local/httpd/virtual/e-paper.elmit.com/htdocs/mainfile.php on line 19

What have I missed? What does it do to the browser?

bye

Ronald

Guess: zlib output cmpression is being turned on in your php.ini and you're
trying to se ob_gzhandler in your ob_start in mainfile.php on line 19, which
would basically ask PHP to compress your output twice.
; You can redirect all of the output of your scripts to a function. For
; example, if you set output_handler to "mb_output_handler", character
; encoding will be transparently converted to the specified encoding.
; Setting any output handler automatically turns on output buffering.
; Note: People who wrote portable scripts should not depend on this ini
; directive. Instead, explicitly set the output handler using
ob_start().
; Using this ini directive may cause problems unless you know what
script
; is doing.
; Note: You cannot use both "mb_output_handler" with "ob_iconv_handler"
; and you cannot use both "ob_gzhandler" and "zlib.output_compression".
;output_handler =

effects on browser: dunno. depends on whether php obeys you without question
or tries to cover up your mistake.

solution: your output is already being compressed. don't try to do it again in
mainfile.php
