If you want to remove all whitespace:

$str = preg_replace('/\s+/', '', $yourstring);

Use the trim function to do this.

return(trim($str));

This is the most elegant *looking*, but wouldn't you have to break it up by newline characters first, if it's all in one variable? – Cameron Hurd Nov 14 '17 at 13:12
