note 124427 added to function.error-log

You can easily filter messages sent to error_log() using "tail" and "grep" on *nix systems. This makes monitoring debug messages easy to see during development. Be sure to "tag" your error message with a unique string so you can filter it using "grep": In your code: error_log("DevSys1 - FirstName: $FirstName - LastName: $Lastname"); On your command line: tail -f /var/log/httpd/error_log | grep DevSys1 In this example, we pipe apache log output to grep (STDIN) which filters it for you only showing messages that contain "DevSys1". The "-f" option means "follow" which streams all new log entries to your terminal or to any piped command that follows, in this case "grep". ---- Server IP: 208.43.231.9 Probable Submitter: 82.199.157.54 (proxied: 198.133.167.85) ---- Manual Page -- http://php.net/manual/en/function.error-log.php Edit -- https://master.php.net/note/edit/124427 Del: integrated -- https://master.php.net/note/delete/124427/integrated Del: useless -- https://master.php.net/note/delete/124427/useless Del: bad code -- https://master.php.net/note/delete/124427/bad+code Del: spam -- https://master.php.net/note/delete/124427/spam Del: non-english -- https://master.php.net/note/delete/124427/non-english Del: in docs -- https://master.php.net/note/delete/124427/in+docs Del: other reasons-- https://master.php.net/note/delete/124427 Reject -- https://master.php.net/note/reject/124427 Search -- https://master.php.net/manage/user-notes.php
