print_r replacement

[Boofo]

I just found this little snippet of code that works great for replacing print_r when working with code, and thought I would share it here. It prints out like this:

Array
(
    [0] => 5
    [1] => 6
    [2] => 7
)

Here is the code:

PHP Code:

if (!function_exists("preprint")) {
     function preprint($s, $return=false) {
         $x = "<pre>";
         $x .= print_r($s, 1);
         $x .= "</pre>";
         if ($return) return $x;
         else print $x;
     }
 } 


@usage:

PHP Code:

preprint($x);   <- where $x = array() 


NOTE: The optional 2nd parameter can be set to "true", so the html-code is returned.

I haven't quite figured out what the 2nd perimeter actually does as no code has shown up for me when that has been enabled.
