A simple usage example:



<?php

header('Content-type: text/xml; charset=UTF-8');



$oXMLWriter = new XMLWriter;

$oXMLWriter->openMemory();

$oXMLWriter->startDocument('1.0', 'UTF-8');



$oXMLWriter->startElement('test');

$oXMLWriter->text('Hello, World!');

$oXMLWriter->endElement();



$oXMLWriter->endDocument();

echo $oXMLWriter->outputMemory(TRUE);

?>

Here is an simple example of using openMemory. This is particularly useful when you are handling a large amount of data and you want to split the xml creation in batches.



<?php

$batchSize = 25;

$xmlWriter = new XMLWriter();

$xmlWriter->openUri('php://output');

$xmlWriter->setIndent(true);

if($xmlWriter)

{

  $xmlWriter->startDocument('1.0','UTF-8');

  $xmlWriter->startElement('Books');

  

  $memXmlWriter = new XMLWriter();

  

  $memXmlWriter->openMemory();

  $memXmlWriter->setIndent(true);

  

  for($i=1;$i<=1000;$i++)

  {

    $memXmlWriter->startElement('book');

      $memXmlWriter->text('book_'.$i);

    $memXmlWriter->endElement();

    

    if($i%5 == 0)

    {

      $batchXmlString = $memXmlWriter->outputMemory(true);

      $xmlWriter->writeRaw($batchXmlString);

    }

  }

  $memXmlWriter->flush();

  unset($memXmlWriter);

  $xmlWriter->endElement();

  $xmlWriter->endDocument();  

}

?>
