示例

以下示例演示了 xmlwriter_text() 函式的使用 -

<?php
   //Creating an XMLWriter
   $writer = new XMLWriter();
   $uri = "result.xml";

   //Opening a writer
   $writer = xmlwriter_open_uri($uri);

   //Starting the document
   xmlwriter_start_document($writer);

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

   //Setting the attribute 
   xmlwriter_write_attribute($writer, 'attr', 'test_value');

   //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);
?>

這將生成以下 XML 文件 -

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

示例

以下是此函式在面向物件風格中的示例 -

<?php

   $writer = new XMLWriter();
   $uri = "result.xml";

   //Opening a writer
   $writer->openUri($uri);

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

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

   //Setting the attribute 
   $writer->writeAttribute('attr', 'test_value');

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

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

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

這將生成以下 XML 文件 -

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