No? The first writelock was denied because there was still a readlock in place.
var_dump($readwrite->readlock(0)); // shared lock #1 - true
var_dump($readwrite->readlock(0)); // shared lock #2 - true
var_dump($readwrite->readunlock()); // unlocked #2 - true
var_dump($readwrite->writelock(0)); // still locked by #1 - false <<<
var_dump($readwrite->readunlock()); // unlock #1 - true
var_dump($readwrite->readunlock()); // not locked - false
var_dump($readwrite->writelock(0)); // exclusive lock #1 - true
var_dump($readwrite->writelock(0)); // locked by #1 - false
var_dump($readwrite->readlock(0)); // locked by #1 - false
var_dump($readwrite->writeunlock()); // unlock #1 - true

Description:
------------
In the tests\014.phpt, the last fourth expect result should be bool(false), not
bool(true), because the fourth writelock has not unlocked.
var_dump($readwrite->readlock(0));
var_dump($readwrite->readlock(0));
var_dump($readwrite->readunlock());
var_dump($readwrite->writelock(0));
var_dump($readwrite->readunlock());
var_dump($readwrite->readunlock());
var_dump($readwrite->writelock(0));
var_dump($readwrite->writelock(0));
var_dump($readwrite->readlock(0));
var_dump($readwrite->writeunlock());
?>
--EXPECT--
bool(true)
bool(true)
bool(true)
bool(false)
bool(true)
bool(false)
bool(true) <----Here should be false
bool(false)
bool(false)
bool(true)
