Few days back I was working on a live wordpress site and need to debug some code, as it was live I can’t add some echo’s and exit so I added email code and then check the emails continuesly, then I reliaze I need a logging mechanism and I made this simple logging plugin, which will log my debugging code and its easy to compare anything there rather then in emails.
Call debug log plugin create a log file date wise in the wp-content/logs directory, you just need to add this plugin, activate it and call
$content = “This content needs to be logged ”;
do_action(‘calldebuglog’, $content);
where $content is any debug code you want to check in the log file, and “calldebuglog” is hook which will call the required function.

Let me know your views and thoughts on this.
It’s just idea, but maybe you could add echoes as HTML comments. This way, output will not be visible to the visitor, but you will see output if you peek to the page source during the debugging time.
