May be suexec thing. Please try 5.5 or 5.4. ------------------------------------------------------------------------ [2012-09-12 17:56:16] connie at jaygoss dot com I just encountered this bug on version 5.3.13. The script worked fine for about a year, then stopped working for no known reason (no code changes, version upgrades, etc.) This script works: echo "<br>Flock Test Without Session<br>"; $fp = fopen("_order_id.txt", "r+"); if (flock($fp, LOCK_EX)) { /* do an exclusive lock to get an order number */ $id = fread($fp,filesize("_order_id.txt")); $id++; echo "<br>Got the lock, id is now $id"; ftruncate($fp, 0); /* truncate file */ rewind($fp); /* reset pointer */ fwrite($fp, $id); /* write new order id */ flock($fp, LOCK_UN); /* release the lock */ } else { echo "Couldn't get the lock"; } However, if I put the same code inside a session, it fails on my live site, but still works fine in my localhost (version 5.3.8): session_start(); echo "<br>Flock Test With Session<br>"; $fp = fopen("_order_id.txt", "r+"); if (flock($fp, LOCK_EX)) { /* do an exclusive lock to get an order number */ $id = fread($fp,filesize("_order_id.txt")); $id++; echo "<br>Got the lock, id is now $id"; ftruncate($fp, 0); /* truncate file */ rewind($fp); /* reset pointer */ fwrite($fp, $id); /* write new order id */ flock($fp, LOCK_UN); /* release the lock */ } else { echo "Couldn't get the lock"; } session_destroy(); ------------------------------------------------------------------------ [2012-09-12 03:14:57] ahar...@php.net Explanation provided separately, since it's not relevant to this bug. Bug reopened. ------------------------------------------------------------------------ [2012-09-12 03:10:26] larue...@php.net ...maybe it's chagned by the reporter self, no action history log in the changes tab ------------------------------------------------------------------------ [2012-09-11 20:39:24] kriscr...@php.net Could somebody explain why the status was changed to "Not a bug?" I'm not seeing anything in the comments to indicate why that edit was made. Looks like a real bug to me and everything else seems to check-out, so I'm assuming that was an error given the lack of an explanation. I'm re-opening this with "Feedback" status. If you're the one who closed this (the edit history is empty), please post a comment explaining your reasoning. Thanks! ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
