XMLWriter::endDtdAttlist()函數是PHP中的內置函數,用於結束當前DTD AttList。 DTD代表“文檔類型定義”,它定義了XML文檔的結構以及法律元素和屬性。 DTD在網頁中不可見,因為它們的作用類似於注釋。在DTD中,使用ATTLIST聲明來聲明屬性。
用法:
bool XMLWriter::endDtdAttlist( void )
參數:此函數不接受任何參數。
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::endDtdAttlist()函數:

$writer = new XMLWriter();
// Create the output stream as PHP

// Start the document
$writer->startDocument('1.0', 'UTF-8');
// Start the Dtd Attlist
$writer->startDtdAttlist('geeksforgeeks');
// End the Dtd Attlist
$writer->endDtdAttlist();
// End the document
$writer->endDocument();
?>
輸出:
<?xml version="1.0" encoding="UTF-8"?> <!ATTLIST geeksforgeeks>
範例2:
<?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');

// Add text to document
$writer->text('geeksforgeeks');
