Description:
------------
I use PHP for some UDP gamequery scripts. Everything works OK in PHP 4.x, but the new PHP 5 RCs' fread() seems to act greedily once again. Checked the CVS version (Jun 11, 2004 06:30 GM) - the same.

I think it is a duplicate of (or very similar to) Bug #15639 (detecting end of UDP packets) which was fixed in PHP 4.3.2.

Reproduce code:
---------------
// Just an example query
// :1 - blocking socket
$handle = fsockopen("udp://195.149.21.70", 27015);
fwrite($handle, "\xFF\xFF\xFF\xFFrules\x00");
$data = fread($handle, 8192);
// It just hangs

// :2 - non-blocking socket
$handle = fsockopen("udp://195.149.21.70", 27015);
stream_set_blocking($handle, FALSE);
fwrite($handle, "\xFF\xFF\xFF\xFFrules\x00");
sleep(1);
$data = fread($handle, 8192);
// Returns more than 1 packet

Expected result:
----------------
Should work just as in PHP 4.3.7:
Case 1 - blocking socket:
Returns the less of one packet or max length.
Case 2 - non-blocking:
Returns just one packet.
