   xmlwriter_set_indent($writer, TRUE);
   xmlwriter_set_indent_string($writer, "    ");

   //Starting the Dtd Attlist tag
   xmlwriter_start_dtd_attlist($writer, 'sample_dtd_att_list');

   //Ending the Dtd Attlist tag
   xmlwriter_end_dtd_attlist($writer); 

   //Starting an element
   xmlwriter_start_element($writer, 'Tutorial');

   //Starting a namespaced element tag
   xmlwriter_start_element($writer, 'name');

   //Adding text to the element
   xmlwriter_text($writer, 'JavaFX');  
   xmlwriter_end_element($writer);

<?php
   //Creating an XMLWriter
   $writer = new XMLWriter();

   //Opening a writer
   $uri = "result.xml";
   $writer->openUri($uri);

   //Starting the document
   $writer->startDocument();

   //Setting the indentation on
   $writer->setIndent(TRUE);
   
   //Setting the indentation
   $writer->setIndentString("    ");

   //Starting the Dtd Attlist tag
   $writer->startDtdAttlist('sample_dtd_att_list');

   //Ending the Dtd Attlist tag
   $writer->endDtdAttlist(); 

   //Starting an element
   $writer->startElement('Tutorial');
   $writer->startElement('name');
   
   //Adding text to the element
   $writer->text('JavaFX');  
   $writer->endElement();

   $writer->startElement('Author');
   //Adding text to the element
   $writer->text('Krishna');  
   $writer->endElement();

   //Ending the element
   $writer->endElement();
   //Ending the document
   $writer->endDocument();
?> 

This will generate the following XML document −

<?xml version="1.0"?>
<!ATTLIST sample_dtd_att_list>
<Tutorial>
   <name>JavaFX</name>
   <Author>Krishna</Author>
</Tutorial>
