示例

以下示例演示了 xmlwriter_output_memory() 函式的用法：

<?php
   //Opening a writer
   $writer = xmlwriter_open_memory();

   //Starting the document
   xmlwriter_start_document($writer);

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

   //Adding text to the element
   xmlwriter_text($writer, 'Welcome to Tutorialspoint');  

   //Ending the element
   xmlwriter_end_element($writer);

   //Ending the document
   xmlwriter_end_document($writer);

   $res = xmlwriter_output_memory($writer);
   print($res);
?>

這將生成以下 XML 文件：

<?xml version="1.0"?>
<Msg>Welcome to Tutorialspoint</Msg>

示例

以下是此函式的面向物件風格示例：

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

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

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

   //Starting an element
   $writer->startElement('Msg');

   //Adding text to the element
   $writer->text('Welcome to Tutorialspoint');  

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

   //Ending the document
   $writer->endDocument();
   $res = $writer->outputMemory();
   print($res);
?>

這將生成以下 XML 文件：

<?xml version="1.0"?>
<Msg>Welcome to Tutorialspoint</Msg>
