New Comment:
Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at
http://www.php.net/manual/ and the instructions on how to
report
a bug at http://bugs.php.net/how-to-report.php
From the manual (http://nl3.php.net/flock):
PHP supports a portable way of locking complete files in an advisory
way (which means all accessing programs have to use the same way of
locking or it will not work).
Not a bug -> bogus

hello,
Chen i use flocks on Linux, it is always possible to write or read the
locked file.
Script:
<?php
$fp = fopen ( 'lock.tmp', 'a+');
if( flock ( $fp, LOCK_EX ) ) {
fwrite ( STDOUT, "Lock good...\n");
} else {
fwrite ( STDOUT, "Error getting Lock...\n");
}
sleep ( 30 );
if( flock ( $fp, LOCK_UN ) ) {
fwrite ( STDOUT, "Lock release good...\n");
} else {
fwrite ( STDOUT, "Error released Lock...\n");
}
?>
during sleep, i run "echo test >> lock.tmp" under shell.
And it is works fine.
On windows 2000, it is seems to works.
