Here's a "pretty print" var_dump

function vdump() {

    $args = func_get_args();

    $backtrace = debug_backtrace();
    $code = file($backtrace[0]['file']);    

    echo "
";

    echo "".htmlspecialchars(trim($code[$backtrace[0]['line']-1]))."\n";

    echo "\n";

        ob_start();

            foreach ($args as $arg)
                var_dump($arg);

            $str = ob_get_contents();

        ob_end_clean();

        $str = preg_replace('/=>(\s+)/', ' => ', $str);
        $str = preg_replace('/ => NULL/', ' → NULL', $str);
        $str = preg_replace('/}\n(\s+)\[/', "}\n\n".'$1[', $str);
        $str = preg_replace('/ (float|int)\((\-?[\d\.]+)\)/', " $1 $2", $str);

        $str = preg_replace('/array\((\d+)\) {\s+}\n/', "array•$1 []", $str);
        $str = preg_replace('/ string\((\d+)\) \"(.*)\"/', " str•$1 '$2'", $str);
        $str = preg_replace('/\[\"(.+)\"\] => /', "'$1' → ", $str);
        $str = preg_replace('/object\((\S+)\)#(\d+) \((\d+)\) {/', "obj•$2 $1[$3] {", $str);
        $str = str_replace("bool(false)", "bool•false", $str);
        $str = str_replace("bool(true)", "bool•true", $str);

        echo $str;

    echo "
";

    echo "

        echo "Sizes: ";
        foreach ($args as $k => $arg) {

            if ($k > 0) echo ",";
            echo count($arg);

        }

    echo "
