I saw that it puts all the processed data in buffer, and releases when complete.
What exactly is buffer? I only saw this name on players, which is the size of the file that will be allocated in memory from the current video/audio point.
What I understood, is that the page is only released when the data is all processed, like, goes all at once to the client. That’s right?
The doubt is good, so I gave +1 in the question, but it is basically what was answered in the indicated link, so the closure indicating the solution. Note that theob_ prefix is just "output buffer"
