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 have to call the function and apply echo on the returned value:

 $thisXml = '…';
 echo getThisXML($thisXml);

Or you pass the variably by reference.
