Output buffering in PHP buffers a scripts output. This buffer can be edited before returning it to the client. Without output buffering, PHP sends data to the web server as soon as it is ready. Output buffering "send" cookies at any point in the script. Cookies do not have to be necessarily sent near the start of page. Output buffers are stackable and hence sending to output is by choice.

PSRs are PHP Standards Recommendations that aim at standardizing common aspects of PHP Development.

An example of a PSR is PSR-2, which is a coding style guide.
