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 need to invoke the function!

$thisXml = 'xml declaration stuff';

echo getThisXML($thisXML);

Or pass the variable by reference:

$thisXml = 'xml declaration stuff';

function getThisXML(&$thisXML){
  ...
  return $thisXml;
}

getThisXML($thisXML);
echo $thisXml;
