Mac popup notification for a PHP error

Receive a notification when PHP errors are logged on Mac

I have PHP configured to log all of its errors to a single log file. I always have Terminal open and tail watching this file. However, sometimes I don’t realize that new errors have been logged right away, which is annoying. To overcome this, I thought it would be nice if I could get a popup notification each time there was an error, just like many Mac apps do. I found this thread on SO, which helped me solve my problem.

If you have Homebrew installed, all you need to do is run:

$ brew install terminal-notifier
$ brew install fswatch

Then add this function to your .bash_profile:

notify-php-logs() {
	fswatch -0 ~/zebug.log | xargs -0 -n 1 \
		terminal-notifier -title "PHP Error" \
			-message "New errors in zebug.log" \
			-group "php-errors" \
			-activate "com.apple.Terminal"
}

Then run:

$ notify-php-logs >/dev/null 2>&1 &
$ tail -f ~/zebug.log

You’ll want to replace ~/zebug.log with the path of the log file that you want to listen to, of course.

Now whenever there is a PHP error, you will get a notification, and when you click on it the Terminal app will be brought to the front so you can see the error.

The Law of Software Thermodynamics

I just found this quote, and I wanted to save it for reference:

There’s this little law of thermodynamics that says energy is neither created nor destroy[ed], it just changes form. This law almost holds true for complexity in software development – except that we can and do create complexity in our systems. And it seems that once we create the complexity, it never seems to get destroyed. It only gets moved around.
