It appears that this does not work with numbered entities, only named entities.
$nbspace = $dom->createEntityReference('nbsp');
works
$nbspace = $dom->createEntityReference('#160');
does not. This makes this function rather useless when generating an XSL unless you modify the XSL doctype to include the named entity for the character you want.<?php
/*Entity is a group of words which print a special symbol.
Like if we want to show copy right symbol in html page then we use © code and browser convert this to actual copyright symbol.
There have lots of entity, you can find them all form http://dev.w3.org/html5/html-author/charref
if you want to use < or > or both <> into a node value than xml will give and warning or make this value as a node.
So tell the xml parser that < or > is not tag symbol it is a entity.To do that you have to right <(<) and >(>) instead of < and > symbol.
Entity references always begin with an ampersand (&) and end with a semicolon (;).
DO not need to use & and ; symbol begin and end of entity.Remove it when you want to use it to DOMDocument::createEntityReference
Then append to to a tag where you want to show this symbol.Like below
*/
$dom=new DOMDocument("1.0","UTF-8");
$example=$dom->createElement("example","This is copyright ");
$entity=$dom->createEntityReference("copy");
$example->appendChild($entity);
$dom->appendChild($example);
echo $dom->saveXML();
output is
This is copyright ยฉ
