Throughout development many of us use the built-in error_log() function quite a bit. I know I sure do when I am debugging models, controllers, and the such but don't you hate it when you want to write the contents of an array or object to the error log? The error_log() function only accepts a string parameter so we have to use a little trick when we want to output array/object contents. We can accomplish this using only a few lines of code:

While this is nothing ground breaking, it's certainly a handy trick when you are trying to debug code that deals with arrays and objects.
