dBug is a class for PHP programmers to output variables, object and even XML in a better looking way than var_dump. It uses great CSS and JavaScript to make the output easier to access, like expand an array. Here is an example of the output:

include("dBug.php");
$variable = array(
    "first"=>"1",
    "second",
    "third"=>array(
        "inner third 1",
        "inner third 2"=>"yeah"),
    "fourth");
 
new dBug($variable1);

Editor Comment:

I was using array2table and var_dump, print_r before I thought about making my own. Then I got to know dBug, so I know I don't have to make my own that will cost me over 20 hours.
