That is also true for the string of zero length and the NULL value, because 
that is their string representation (the result of converting them to the 
string type).  PHP 101.

With Xdebug so configured and loaded, var_dump() also has the advantage over 
print_r() that it prints colored output, prepends '<pre>' and appends 
'</pre>', and limits by default the output for nested arrays.
