note 105879 added to function.flock

I just spend a long time to understand why write function returns me "0", on a basic file opening and then writing. I discovered that if you use LOCK_SH and then you write something, that will not work : $fp = fopen('file.txt', 'a'); flock($fp,LOCK_SH); $written = fputs($fp, 'data'); var_dump($written); // 0 and file is not changed fclose($fp); ---- Server IP: 69.147.83.197 Probable Submitter: 80.236.234.148 ---- Manual Page -- http://www.php.net/manual/en/function.flock.php Edit -- https://master.php.net/note/edit/105879 Del: integrated -- https://master.php.net/note/delete/105879/integrated Del: useless -- https://master.php.net/note/delete/105879/useless Del: bad code -- https://master.php.net/note/delete/105879/bad+code Del: spam -- https://master.php.net/note/delete/105879/spam Del: non-english -- https://master.php.net/note/delete/105879/non-english Del: in docs -- https://master.php.net/note/delete/105879/in+docs Del: other reasons-- https://master.php.net/note/delete/105879 Reject -- https://master.php.net/note/reject/105879 Search -- https://master.php.net/manage/user-notes.php
