Returning a variable from a function in php (return not working)

Question

I\'m building an XML page inside of a function, and for some strange reason I don\'t get the whole thing spit out of the function. I\'ve tried

return $thisX         


        

Answer 1

You are trying to use a variable defined inside the function scope.

Use:

$thisXML;

function do(){
 global $thisXML;
 $thisXML = "foobar";
}

print $thisXML;
