想问大家一个phpcms梨奇怪的问题
以下代码是我从phpcms的libs\function\global.func.php文件中复制来的。
function menu_level($menuid, $cache_file, $cache_path = 'commons', $key = 'catname', $parentkey = 'parentid', $linkstring = ' > ', $result=array()) { $menu_arr = getcache($cache_file, $cache_path); if (array_key_exists($menuid, $menu_arr)) { $result[] = $menu_arr[$menuid][$key]; return menu_level($menu_arr[$menuid][$parentkey], $cache_file, $cache_path, $key, $parentkey, $linkstring, $result); } krsort($result); return implode($linkstring, $result);}
这个方法是用来从缓存里获取数据数组,然后用指定的链接符号进行链接的方法,相信用过phpcms的同志们应该见到过。这个方法会递归3次,我这里出现了一个奇怪的问题,就是当
$menu_arr[$menuid][$parentkey]的值等于0的时候,menu_level方法的递归便不再进行了。
本地没有问题,服务器上就会出这个问题。
有人碰到过这个问题吗?
回复讨论(解决方案)
只有当 $menu_arr[$menuid] 存在时,递归才会进行下去
至于 $menu_arr[$menuid] 是否存在,则取决于你的缓存文件

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,

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.
