SimpleXML在php中怎样实现属性操作

SimpleXML在PHP中可以通过以下方法实现属性操作：

1. 获得属性的值：

$xml = '<bookstore><book category="fiction">PHP Basics</book></bookstore>';
$books = simplexml_load_string($xml);
$category = $books->book['category'];
echo $category; // 输出: fiction

2. 设置属性的值：

$xml = '<bookstore><book category="fiction">PHP Basics</book></bookstore>';
$books = simplexml_load_string($xml);
$books->book['category'] = 'non-fiction';
echo $books->asXML(); // 输出: <bookstore><book category="non-fiction">PHP Basics</book></bookstore>

3. 删除属性：

$xml = '<bookstore><book category="fiction">PHP Basics</book></bookstore>';
$books = simplexml_load_string($xml);
unset($books->book['category']);
echo $books->asXML(); // 输出: <bookstore><book>PHP Basics</book></bookstore>
