怎么输出为这样的
<select><option value="8">111111</option><option value="13">*121212</option><option value="14">*32323232</option><option value="9">22222222</option><option value="10">*333333</option><option value="11">**44444444</option><option value="12">***555555</option><option value="17">***werwerwer</option><option value="19">**6565656</option><option value="15">*23232323</option><option value="16">**324234234</option></select>
sonclass 是包含的子类id 怎么能树状循环出html这样的效果? 我只会输出一层 没办法向这样有子分类就一直循环输出出来
回复讨论(解决方案)
你这里不需要子id,有父id就行啦,你根据classid查询子id就行了
有父id,featherclass=classid,就能到到classid的下级
你这是想做什么??
有父id,featherclass=classid,就能到到classid的下级
可以写出具体点的吗 感谢!!
$class = $this->tclass->get_all_class($this->tbname); $json_class = Array(); $json_class2 = array(); foreach ($class as $key=>$value) { if($class[$key]['sonclass']) //如果有子分类 { $json_class[$key]['id'] = $value['classid']; $json_class[$key]['text'] = $value['classname']; $son_arr = $this->tclass->get_son_class($value['sonclass'],$this->tbname); foreach ($son_arr as $k=>$v) { $json_class1[$k]['id'] = $v['classid']; $json_class1[$k]['text'] = $v['classname']; } $json_class[$key]['children'] = $json_class1; } }
我这样只能得出父和一层子 怎么能循环得出子类?

PHP remains a powerful and widely used tool in modern programming, especially in the field of web development. 1) PHP is easy to use and seamlessly integrated with databases, and is the first choice for many developers. 2) It supports dynamic content generation and object-oriented programming, suitable for quickly creating and maintaining websites. 3) PHP's performance can be improved by caching and optimizing database queries, and its extensive community and rich ecosystem make it still important in today's technology stack.

In PHP, weak references are implemented through the WeakReference class and will not prevent the garbage collector from reclaiming objects. Weak references are suitable for scenarios such as caching systems and event listeners. It should be noted that it cannot guarantee the survival of objects and that garbage collection may be delayed.

The \_\_invoke method allows objects to be called like functions. 1. Define the \_\_invoke method so that the object can be called. 2. When using the $obj(...) syntax, PHP will execute the \_\_invoke method. 3. Suitable for scenarios such as logging and calculator, improving code flexibility and readability.

Fibers was introduced in PHP8.1, improving concurrent processing capabilities. 1) Fibers is a lightweight concurrency model similar to coroutines. 2) They allow developers to manually control the execution flow of tasks and are suitable for handling I/O-intensive tasks. 3) Using Fibers can write more efficient and responsive code.

The PHP community provides rich resources and support to help developers grow. 1) Resources include official documentation, tutorials, blogs and open source projects such as Laravel and Symfony. 2) Support can be obtained through StackOverflow, Reddit and Slack channels. 3) Development trends can be learned by following RFC. 4) Integration into the community can be achieved through active participation, contribution to code and learning sharing.

PHP and Python each have their own advantages, and the choice should be based on project requirements. 1.PHP is suitable for web development, with simple syntax and high execution efficiency. 2. Python is suitable for data science and machine learning, with concise syntax and rich libraries.

PHP is not dying, but constantly adapting and evolving. 1) PHP has undergone multiple version iterations since 1994 to adapt to new technology trends. 2) It is currently widely used in e-commerce, content management systems and other fields. 3) PHP8 introduces JIT compiler and other functions to improve performance and modernization. 4) Use OPcache and follow PSR-12 standards to optimize performance and code quality.

The future of PHP will be achieved by adapting to new technology trends and introducing innovative features: 1) Adapting to cloud computing, containerization and microservice architectures, supporting Docker and Kubernetes; 2) introducing JIT compilers and enumeration types to improve performance and data processing efficiency; 3) Continuously optimize performance and promote best practices.
