smarty 遍历多维数组问题
smarty
Array( [0] => Array ( [0] => 1 [id] => 1 [1] => 设置 [name] => 设置 [2] => 0 [parentid] => 0 [child] => Array ( [0] => Array ( [0] => 20 [id] => 20 [1] => 管理员管理 [name] => 管理员管理 [2] => 1 [parentid] => 1 [child] => Array ( [0] => Array ( [0] => 23 [id] => 23 [1] => 角色管理 [name] => 角色管理 [2] => 20 [parentid] => 20 ) [1] => Array ( [0] => 22 [id] => 22 [1] => 管理员管理 [name] => 管理员管理 [2] => 20 [parentid] => 20 ) ) ) [1] => Array ( [0] => 19 [id] => 19 [1] => 相关设置 [name] => 相关设置 [2] => 1 [parentid] => 1 [child] => Array ( [0] => Array ( [0] => 25 [id] => 25 [1] => 模型管理 [name] => 模型管理 [2] => 19 [parentid] => 19 ) [1] => Array ( [0] => 24 [id] => 24 [1] => 菜单管理 [name] => 菜单管理 [2] => 19 [parentid] => 19 ) [2] => Array ( [0] => 21 [id] => 21 [1] => 基本设置 [name] => 基本设置 [2] => 19 [parentid] => 19 ) ) ) ) )
<{foreach from=$arr item=m}> ID: <{$m.id}> <{$m.name}> <{$m.id}><br> <{foreach from=$m.child item=item}> <{$item.name}> <{$item.id}><br> <{foreach from=$item.child item=items}> <{$items.name}> <{$items.id}><br> <{/foreach}> <{/foreach}> <{/foreach}>
如何遍历多维数组呢? 如果再有下级,smarty 应该如何遍历无限多?
回复讨论(解决方案)
你需要递归遍历数组,以下面的例子为参考,自己改个smarty版的
function bianli($array){ foreach($array as $value){ if(is_array($value)){ bianli($value); }else{ echo $value."\n"; } } } $a=array('A','B',array('c','d',array('e','f')),'g'); echo bianli($a);
不考虑用:smarty 实现递归了
用php递归实现
smarty只实现了一些基础的功能,高级功能需要写插件

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,

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.

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.
