Code: Select all
function xml() { return "<?xml version=\"1.0\" encoding=\"ISO-8859-1\"?> \n"; }
function doctype(){ return '<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN" "http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd"> \n'; }
Why is this and what and where I could read about it. Googleing for single or double quote, escapes, leads me to nowhere...
