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

return $thisXml;
}
echo $thisXML;

$thisXML; only exists in the scope of the function. Either make $thisXML; global (bad idea) or echo getThisXML() where getThisXML is the function that returns $thisXML;
