What does "1" mean at the end of a php print_r statement?

Question

My print_r($view) function yields:

View Object
(
    [viewArray:View:private] => Array
        (
            [title] => Projet JDelage
        )
)
1 <--------------

What does the "1" at the end mean? The PHP manual isn't very clear on how to parse the output of print_r.

Answer 1

You probably have echo print_r($view). Remove the echo construct. And... what need do you have to parse its output? There are certainly much better ways to solve your problem.
