Description: These are two small functions which output
variable type and content in a nice formatted way. Actually it uses var_dump(), but encloses the outtput in <hr>’s and uses a
fixed-width font. Arrays are parsed recursively and every new instance is indented by a given number of ’s.
It only ‘debugs’ if a variable named $debug is set to ‘true’, so you can easily switch on or off the output globally.
