以上数据库表的内容怎么用php+mysql输出以下内容
//首先是MYSQL查询,这里就只写SQL语句了
$sql="select 字段1,字段2 from 表名 where 条件";
$result=$mysqli->query($sql);
//然后再把符合条件的记录取出来,赋值到一个变量里
$rs1=$result->fetch_assoc();
$rs2=$result->fetch_assoc();
//然后再输出
echo "
如果出现 大分类2 ,打算怎么输出?
如果出现 大分类2 ,打算怎么输出?
2楼的方法不行啊 如果以后要添加 不是生成不了了
$rs = mysql_query('select * from 表 order by 1, 2');$last = '';echo '<div>';where($r = mysql_fetch($rs)) { if($r['字段1'] != $last) { echo "<div>{$r['字段1']}</div>"; $last = $r['字段1']; } echo "<div>{$r['字段2']}</div>";}

Article discusses late static binding (LSB) in PHP, introduced in PHP 5.3, allowing runtime resolution of static method calls for more flexible inheritance.Main issue: LSB vs. traditional polymorphism; LSB's practical applications and potential perfo

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.

Static binding (static::) implements late static binding (LSB) in PHP, allowing calling classes to be referenced in static contexts rather than defining classes. 1) The parsing process is performed at runtime, 2) Look up the call class in the inheritance relationship, 3) It may bring performance overhead.
