Why save output until the end?

output-buffering

Very quick question about programming practices here:

I've always used echo() to output HTML code to the user as soon as it was generated, and used ob_start() at the same time to be able to output headers later in the code. Recently, I was made aware that this is bad programming practice and I should be saving HTML output until the end.

Is there a reason for this? What is it, and why isn't output buffering a good alternative?

Thanks!

So a FILE stream can have both input and output buffers. You can adjust the output stream using setvbuf (I am unaware of any method to play with the input buffer size and behavior). Also, by default the buffer is BUFSIZ (not sure if this is a POSIX or C thing). It is very clear what this means for… >>> More
