?>
复制代码 代码如下:
复制代码 代码如下:
$xml = simplexml_load_file('example.xml'); //创建SimpleXML对象
var_dump($xml); //输出XML
?>
复制代码 代码如下:
$xml = simplexml_load_file('example.xml'); //读取XML文件
foreach($xml->depart as $a) //循环读取XML数据中的每一个depart标签
{
echo "$a->name
"; //输出其中的name属性
}
?>
复制代码 代码如下:
$xml = simplexml_load_file('example.xml'); //读取XML文件
echo $xml->depart->name[0]; //输出节点
?>
复制代码 代码如下:
$xml = simplexml_load_file('example.xml');
foreach ($xml->depart->children() as $depart) //循环读取depart标签下的子标签
{
var_dump($depart); //输出标签的XML数据
}
?>
复制代码 代码如下:
$xml = simplexml_load_file('example.xml'); //读取XML文件
$result = $xml->xpath('/departs/depart/employees/employee/name'); //定义节点
var_dump($result); //输出节点
?>
复制代码 代码如下:
$xml = simplexml_load_file('example.xml'); //读取XML
$xml->depart->name[0] = "Human Resource"; //修改节点
?>
复制代码 代码如下:
$xml = simplexml_load_file('example.xml'); //读取XML数据
echo $xml->asXML(); //标准化XML数据
?>
复制代码 代码如下:
$xml = simplexml_load_file('example.xml'); //读取XML数据
$newxml = $xml->asXML(); //标准化XML数据
$fp = fopen("newxml.xml", "w"); //打开要写入XML数据的文件
fwrite($fp, $newxml); //写入XML数据
fclose($fp); //关闭文件
?>

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,
