note 55184 added to function.socket-read

I am using php 5.0.4 in WinXP with Apache 2.0.54. When I am trying to use socket_read($sock, 512, PHP_NORMAL_READ) it is giving me error incorrect function argument, but when I am ommiting the PHP_NORMAL_READ flag then the code simply looks like hanging. What should I do? ---- Manual Page -- http://www.php.net/manual/en/function.socket-read.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+55184 Delete: added to the manual -- http://master.php.net/manage/user-notes.php?action=delete+55184&report=yes&reason=added+to+the+manual Delete: bad code -- http://master.php.net/manage/user-notes.php?action=delete+55184&report=yes&reason=bad+code Delete: spam -- http://master.php.net/manage/user-notes.php?action=delete+55184&report=yes&reason=spam Delete: useless -- http://master.php.net/manage/user-notes.php?action=delete+55184&report=yes&reason=useless Delete: non-english -- http://master.php.net/manage/user-notes.php?action=delete+55184&report=yes&reason=non-english Delete: other reasons -- http://master.php.net/manage/user-notes.php?action=delete+55184&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+55184&report=yes Search -- http://master.php.net/manage/user-notes.php
