is there a flush function in php3?

[Anon]

Hi,

When doing an fwrite to a file, does the input get buffered? The manual says that fwrite just writes the specified number of bytes to the file OR till it reaches the end of the string. If it's the latter case and I do a whole bunch of fwrites, each fwrite is separate, correct? So if I have
fwrite ($fp, "Hello");
fwrite ($fp, "world");
it won't buffer the two fwrites, will it? If it does, is there a flush function in php3? I searched the manual but could not find anything.

Thanks from this newbie.

Please ignore flush question. Didn't see it in the sidebar but actual search did reveal a flush function. Sorry about that.
