fread is allocating memory on its own?

[Ficos <php@xxxxxxxxxxxxxxxxxxx>]

I'm trying to use a PHP script to test the throughput from a few 
different web servers on a test network at work.  I'm doing an fopen 
with the URL, and then a read loop like this:

while (!feof($handle)) {
	fread($handle, 8192);
}

I'm ignoring the data returned by fread, since I'm just interested in 
how long that loop takes, not the contents.  It works fine on small 
files, but once the test file is above PHP's memory limit I get "Allowed 
memory size of 8388608 bytes exhausted (tried to allocate 8192 bytes)".

What I can't figure out is why memory is getting allocated in that loop.

I've also tried doing $string = fread (...) and immediately following 
that with unset($string) or $string = NULL or $string = ''.  None of 
those worked, I still run out of memory.

Any suggestions?
