示例

下面的例子演示了xmlwriter_end_comment()函数 -

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

   //Opening a writer
   $uri = "result.xml";
   $writer = xmlwriter_open_uri($uri);

   //Starting the document
   xmlwriter_start_document($writer);

   //Starting an element
   xmlwriter_start_element($writer, 'Msg');
    
   //Starting the comment 
   xmlwriter_start_comment($writer); 
     
   //Setting value to the comment
   xmlwriter_text($writer, 'This is a sample comment'); 
     
   //Ending the comment 
   xmlwriter_end_comment($writer); 

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

   //Starting an element
   xmlwriter_end_element($writer);

   //Ending the document
   xmlwriter_end_document($writer);
?>

这将生成以下 XML 文档 -

<?xml version="1.0"?>
<Msg><!--This is a sample comment-->Welcome to Tutorialspoint</Msg>

示例

以下是面向对象风格的此函数的示例 -

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

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

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

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

   //Starting the comment 
   $writer->startComment(); 
     
   //Setting value to the comment
   $writer->text('This is a sample comment'); 
     
   //Ending the comment 
   $writer->endComment(); 

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

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

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

这将生成以下 XML 文档 -

<?xml version="1.0"?>
<Msg><!--This is a sample comment-->Welcome to Tutorialspoint</Msg>
