[PHP] periodic file writing error (fputs)
Hello, I am having a periodic problem that I cannot duplicate and wonder if anyone has suggestions. Once a sale is completed a record is written to a log file on the server. $filename = $dir. /. $logType._.$today..txt; $fp = fopen($filename, a+); fputs($fp, $logEntryStr); fclose($fp); The file is chmoded to 644. About 3 out of 600 times, the log file is not written to. The times of day this happens are not consistent, and as I mentioned, I cannot duplicate it when testing. I initially thought it was some kind of error on the server, but I am beginning to think it is in my code. Has anyone experienced anything like this or have any suggestions for how to troubleshoot this?

Do the transactions show up in a database or some other form? Is it possible to have duplicate log entries? What is $today, a date stamp, time date stamp, epoch time stamp? -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

From: Sarah Gray [EMAIL PROTECTED] Once a sale is completed a record is written to a log file on the server. $filename = $dir. /. $logType._.$today..txt; $fp = fopen($filename, a+); fputs($fp, $logEntryStr); fclose($fp); Consider this: 1. User A completes a transaction. 2. Script A reads the log file 3. User B completes a transaction 4. Script B read the log file 5. Script A write the new line to what was read in #2 6. Script B write the new line to what was read in #4 Now what's in the file? Only what Script B wrote. http://us2.php.net/flock ---John Holmes... -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
