Display log messages from PHP in the browser console in Safari, Firefox (with firebug), and Opera (with the new Dragonfly debugging environment). Essential debugging tool for 
plugin and theme developers. You no longer have to use ‘print_r’ statements from PHP to figure out what is going 
on in the code, which more often than not, messes up the DOM and HTML layout. Displays complex PHP structures like arrays and objects 
in pretty print.
