If you have a complex project going, it’s helpful to extend item #4 to use a range of $debug_level values (e.g. 0 to 3) so that you can include a boatload of debug messages when you need to see everything at level 3, and use level 1 debug messages when you want to see only a few specific items of your work in progress.

You can also use a global scope function like debug_print( 2, “$foo is dead”) instead of a variable, so you can access it within class scope without global declarations. The current level can be stored however you want, and only the debug function needs to know how and where.

I’ve also thought about merging my logging and debug print functionality, but I don’t need that currently / yet.

Thanks Ninza! This is a great article to start with firephp (http://sixrevisions.com/web-development/how-to-debug-php-using-firefox-with-firephp/). Until the weekend I’ll get your article translated.

Nice tips! One tool that I think is really valuable is FirePHP (http://www.firephp.org/), it’s better than using echo statements to show values.
And if you don’t mind, I’ll translate your article to portuguese in my blog, crediting your article off course.

These are some really good tips. The one thing I would add though is in relation to number 4. There really needs to be a third level of debugging for when the site is live. The debug data can then be commented out into the HTML instead. For example:

= 1) {
if ($debug_check == 1) print “”;
}
?>
