php: using DomDocument whenever I try to write UTF-8 it writes the hexadecimal notation of it

Question

When I try to write UTF-8 Strings into an XML file using DomDocument it actually writes the hexadecimal notation of the string instead of the string itself.

for exam

Answer 1

When I created the DomDocument for writing, i added the following parameters:

dom = new DOMDocument('1.0','utf-8');

these parameters caused the UTF-8 string to be written as is.
