note 80006 added to function.flock

besides from what the manual says about locking a file opendend in w or w+ and using a special lock file for these cases, you should simply truncate the file yourself with ftruncate() after writing: <?php $data='some data'; $handle=fopen('file','r+'); flock($handle,LOCK_EX); fwrite($handle,$data); ftruncate($handle,ftell($handle)); flock($handle,LOCK_UN); fclose($handle); ?> now the file will have the size of $data without opening the file in w mode but with a lock on the file. to the previous writers jpriebe and mallory: of course the lock is lost in this case, but thats simply because the file is closed by PHP. and closing the file means unlocking it (same as when you use fclose() yourself). ---- Server IP: 212.124.37.9 Probable Submitter: 84.166.15.92 ---- Manual Page -- http://www.php.net/manual/en/function.flock.php Edit -- https://master.php.net/note/edit/80006 Del: integrated -- https://master.php.net/note/delete/80006/integrated Del: useless -- https://master.php.net/note/delete/80006/useless Del: bad code -- https://master.php.net/note/delete/80006/bad+code Del: spam -- https://master.php.net/note/delete/80006/spam Del: non-english -- https://master.php.net/note/delete/80006/non-english Del: in docs -- https://master.php.net/note/delete/80006/in+docs Del: other reasons-- https://master.php.net/note/delete/80006 Reject -- https://master.php.net/note/reject/80006 Search -- https://master.php.net/manage/user-notes.php
