ob_get_level() > 1 (should be 0)?

@jaswsinc
Thanks for the note, >0 actually makes sense. Probably during my tests there were always at least 2 output filters active. I will have a look at this again.

Hi,

after further testing, I think i will keep it at 0. The recommended value for “output_buffering” in the php.ini is 4096, which means that there will be always one output buffer (“default output handler” in ob_list_handlers) and the level will be always at least 1.

http://de.php.net/manual/en/outcontrol.configuration.php#ini.output-buffering

php.ini (default for production)

; Output buffering is a mechanism for controlling how much output data
; (excluding headers and cookies) PHP should keep internally before pushing that
; data to the client. If your application's output exceeds this setting, PHP
; will send that data in chunks of roughly the size you specify.
; Turning on this setting and managing its maximum buffer size can yield some
; interesting side-effects depending on your application and web server.
; You may be able to send headers and cookies after you've already sent output
; through print or echo. You also may see performance benefits if your server is
; emitting less packets due to buffered output versus PHP streaming the output
; as it gets it. On production servers, 4096 bytes is a good setting for performance
; reasons.
; Note: Output buffering can also be controlled via Output Buffering Control
;   functions.
; Possible Values:
;   On = Enabled and buffer is unlimited. (Use with caution)
;   Off = Disabled
;   Integer = Enables the buffer and sets its maximum size in bytes.
; Note: This directive is hardcoded to Off for the CLI SAPI
; Default Value: Off
; Development Value: 4096
; Production Value: 4096

output_buffering = 4096

Great, thanks for the feedback.
