`tid` int(10) NOT NULL auto_increment,
`parentID` int(10) DEFAULT '0' NOT NULL,
`LevelID` int(10) DEFAULT '0' NOT NULL,
`imgname` varchar(255) NOT NULL default '',
`imgtitle` varchar(255) NOT NULL default '',
`url` varchar(255) NOT NULL default '',
PRIMARY KEY (`tid`)

然后输出是这样格式的:
请问我的php怎么写呢,我写完感觉无法归类生成xml,php是这样写的,请高手指点,谢谢
include('conn.php');
$result = mysql_query("SELECT * FROM tables");
while($row = mysql_fetch_array($result))
{
if(!$row['parentID'] || $row['parentID']==2){
if($row['LevelID']==2 || $row['parentID']==2){
//echo $row['parentID'] . " " . $row['LevelID']. " " . $row['imgname']. " " . $row['imgtitle']. " " . $row['url']. " " . $i;
//echo "
";
//
}
}
}
回复讨论(解决方案)
你先说说
都对应表中的哪些字段
INSERT INTO tables VALUES ( '1', '0', '1', 'c_1', '按钮','null');
INSERT INTO tables VALUES ( '2', '1', '1', '按钮1', '按钮1','1.jpg');
INSERT INTO tables VALUES ( '3', '1', '2', '按钮2', '按钮2','2.jpg');
其实我就是想从数据库提取数据生成一个xml,xml的格式就是这样的
就不知道如何写个表便于php去读取,怕以后数据多了之后读取变得很慢,谢谢高手指点,谢谢
各位高手,真的没人帮忙吗?

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,

Session hijacking can be achieved through the following steps: 1. Obtain the session ID, 2. Use the session ID, 3. Keep the session active. The methods to prevent session hijacking in PHP include: 1. Use the session_regenerate_id() function to regenerate the session ID, 2. Store session data through the database, 3. Ensure that all session data is transmitted through HTTPS.

The application of SOLID principle in PHP development includes: 1. Single responsibility principle (SRP): Each class is responsible for only one function. 2. Open and close principle (OCP): Changes are achieved through extension rather than modification. 3. Lisch's Substitution Principle (LSP): Subclasses can replace base classes without affecting program accuracy. 4. Interface isolation principle (ISP): Use fine-grained interfaces to avoid dependencies and unused methods. 5. Dependency inversion principle (DIP): High and low-level modules rely on abstraction and are implemented through dependency injection.
