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:
