How to tell if output buffering is on or off?
The output_buffering directive will tell you if Output buffering is on/off. In this case the output_buffering value is 4096 which means that the buffer size is 4 KB. It also means that Output buffering is turned on, on the Web server. It’s possible to turn on/off and change buffer size by changing the value of the output_buffering directive.
What happens when output buffering is turned off in PHP?
If output buffering is turned off, then echo will send data immediately to the Browser. If output buffering is turned on, then an echo will send data to the output buffer before sending it to the Browser. To see whether Output buffering is turned on / off please refer to phpinfo at the core section.
What’s the maximum size of the output buffer?
On production servers, 4096 bytes is a good setting for performance reasons. Note: Output buffering can also be controlled via Output Buffering Control functions. On = Enabled and buffer is unlimited. (Use with caution) Integer = Enables the buffer and sets its maximum size in bytes.

How does buffering control the flow of data?
Through buffering we can control the flow of data to user browser. We can send the date by chunk (or group ) before the complete processing of the page is done or we can send the outputs after the complete script execution is over. Many times we want to send some data for the visitor to read and meanwhile continue the processing of the script.
