print_r Return Value Incorrect

I am having a little trouble with the print_r function. Undoubtedly something I am misunderstanding in its operation... Basically, I have an array of objects in a class like so:

public $fields = array();

Assigned like so:

$oField = new Field();
/* property assignments to $oField omitted for brevity */
$this->fields[$i] = $oField;

Now in the primary class, I am attempting to capture debug information:

$this->debuginfo = print_r($this->fields, true);

When outputting the value of $this->debuginfo, it simply says "Array" - basically not exploding the array. If I do a regular print_r($this->fields);, it gives the expected results.

This is my first time attempting to use print_r with it returning results versus outputting to the screen so I am sure I am just missing something, but in reading the php documentation, this is how it would seem to be implemented. What am I missing?

Thanks for any assistance!

Update: print_r($var, true) does indeed return the "exploded" variable properly as I had it written. Thanks to dev-null for their comment which gave me some food for thought that lead me to my problem.

Try var_export() instead. var_export() gets structured information about the given variable.

example:

$this->debuginfo = var_export($this->fields, true);
