It only happens when started with ob_start('ob_gzhandler');
Even with this test script from the php manual produces this error.
Any insight would be appreciated.
From php.ini ->
; Output buffering allows you to send header lines (including cookies) even
; after you send body content, at the price of slowing PHP's output layer a
; bit. You can enable output buffering during runtime by calling the output
; buffering functions. You can also enable output buffering for all files by
; setting this directive to On. If you wish to limit the size of the buffer
; to a certain size - you can use a maximum number of bytes instead of 'On', as
; a value for this directive (e.g., output_buffering=4096).
output_buffering = 4096
; 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 =
; Transparent output compression using the zlib library
; Valid values for this option are 'off', 'on', or a specific buffer size
; to be used for compression (default is 4KB)
; Note: Resulting chunk size may vary due to nature of compression. PHP
; outputs chunks that are few handreds bytes each as a result of compression.
; If you want larger chunk size for better performence, enable output_buffering
; also.
; Note: output_handler must be empty if this is set 'On' !!!!
; Instead you must use zlib.output_handler.
zlib.output_compression = Off
; You cannot specify additional output handlers if zlib.output_compression ; is activated here. This setting does the same as output_handler but in ; a different order. ;zlib.output_handler =
----------------------------------- Example script ->
<?php
ob_start("ob_gzhandler");
?> <html> <body> <p>This should be a compressed page. </html> <body>
--------------------------------- Error reported ->
This should be a compressed page.
