Php check if output buffering is turned on
|
Is there a simple way to detect in PHP if output_buffering is enabled in php.ini? I'd like to be able to display a message if it is not enabled. Show Within my application I tried using an htaccess file to automatically enable it but it seems it does not work in all server environments and in some cases it gives a nasty error. Thank you very much!

How do I enable output buffering?It's possible to turn on/off and change buffer size by changing the value of the output_buffering directive. Just find it in php. ini , change it to the setting of your choice, and restart the Web server.
What is Ob_start () and Ob_end_flush () in PHP?While output buffering is active no output is sent from the script (other than headers), instead the output is stored in an internal buffer. The contents of this internal buffer may be copied into a string variable using ob_get_contents(). To output what is stored in the internal buffer, use ob_end_flush().
What is the use of Ob_start () in PHP?The ob_start() function creates an output buffer. A callback function can be passed in to do processing on the contents of the buffer before it gets flushed from the buffer. Flags can be used to permit or restrict what the buffer is able to do.
How stop PHP buffering?You can turn on output buffering with ob_start() , and turn it off with ob_end_flush() or ob_end_clean() . You can also have all your scripts automatically start with output buffering on using the output_buffering option in php. ini. The default value of this option for production versions of php.
