flock($fp,2); alwas return false using windows 98. Here a  little testcase:

$fp=fopen ('myfile.txt','a');
if ( $fp != 0 && flock($fp, 2) ){
	fwrite($fp, $mydatas);
} else {
	echo 'error';		
}
fclose($fp);

File locking isn't supported by windows.

Please use the workaround from sbsaylors@yahoo.com:
"Well I needed some kind of "lock" in windows, so I just created a lock.file in that directory. So if anything wants to 'write' to that file (or append, whatever) it checks to see if a lock.file (or whatever name you want to use) is there and if the date of the file is old.  If its old (1 hour) then it deletes it and goes ahead.  If its not old then it waits a random time.  When its finised it deletes the file.

Seems to work alright but I havent tested anything and its only used for maybe a 100 hits a day but... :)"

It would be quite a benefit to incooperate this user contributed note into the manual, reclassifying.

This bug has been fixed in CVS. You can grab a snapshot of the
CVS version at http://snaps.php.net/. In case this was a documentation 
problem, the fix will show up soon at http://www.php.net/manual/.
In case this was a PHP.net website problem, the change will show
up on the PHP.net site and on the mirror sites.
Thank you for the report, and for helping us make PHP better.
