I cant see why you are getting the letter 'z' (assuming $msgContent
was referenced properly) . Complete code will be helpful to debug the
problem.

Also, Heredoc syntax will be more helpful in your situation. And usage
of global keyword is strongly discouraged in favor of $GLOBALS
superglobal array
