XMLWriter::startAttribute()函數是PHP中的一個內置函數,用於啟動屬性。稍後可以使用XMLWriter::endAttribute()函數關閉此屬性。
用法:
bool XMLWriter::startAttribute( string $name )
參數:該函數接受單個參數$name,該參數保存屬性的名稱。
返回值:如果成功,此函數將返回TRUE,否則將返回FALSE。
以下示例說明了PHP中的XMLWriter::startAttribute()函數:
範例1:
<?php 
  
// Create a new XMLWriter instance 
$writer = new XMLWriter(); 
  
// Create the output stream as PHP 
$writer->openURI('php://output'); 
  
// Start the document 
$writer->startDocument('1.0', 'UTF-8'); 
  
// Start a element 
$writer->startElement('div'); 
  
// Start the attribute 
$writer->startAttribute('attrib'); 
  
// Add value to the attribute 
$writer->text('value'); 
  
// End the attribute 
$writer->endAttribute(); 
  
// End the element 
$writer->endElement(); 
  
// End the document 
$writer->endDocument(); 
?>輸出:
<?xml version="1.0" encoding="UTF-8"?> <div attrib="value"/>
範例2:在此示例中,我們將為元素添加樣式
<?php 
  
// Create a new XMLWriter instance 
$writer = new XMLWriter(); 
  
// Create the output stream as PHP 
$writer->openURI('php://output'); 
  
// Start the document 
$writer->startDocument('1.0', 'UTF-8'); 
  
// Start a h1 element 
$writer->startElement('h1'); 
  
// Start the style attribute 
$writer->startAttribute('style'); 
  
// Add value to the attribute 
$writer->text('color:green'); 
  
// End the attribute 
$writer->endAttribute(); 
  
// Add value to the element 
$writer->text('GeeksforGeeks'); 
  
// End the element 
$writer->endElement(); 
  
// End the document 
$writer->endDocument(); 
?>輸出:
