How do I echo saved data outside the function?

Question

I know the data I want is stored as $lineOne and I can echo that inside the function. But I want to get the data outside of the function.

I've tired:

$lineOne; 
$instance['lineOne'];

Here's the code where I want to insert $lineOne (line 11) and the widget where the variable is loaded/saved: http://pastie.org/7142717

toscho -> I do what? If I move the PHP echo code outside the function, it returns nothing — MadsRH, Mar 27, 2013 at 21:20
This is a PHP question not a WordPress one. @MadsRH, you should look into scope. — s_ha_dum, Mar 28, 2013 at 4:17

You'd need to declare $lineOne as global inside your function:

global $lineOne;

Messy way of coding though.

Thanks, I've tired to add global $lineOne; just at the start of the function, but I still cannot echo it outside. Any suggestion regarding the coding style is recived with applause.

This is really general PHP stuff rather than WordPress...
