ThinkPHP使用volist模板赋值问题
今天看代码遇到个问题,给模板赋值是用
assign('变量名','变量值')
<volist name="变量名" id="循环量">xxx </volist>
但是我遇到了变量名好像不一样啊。
<ul class="main-nav"> <volist name="__MENU__.main" id="menu"> <li class="{$menu.class|default=''}"><a href="{$menu.url|U}">{$menu.title}</a></li> </volist> </ul>
$this->assign('__MENU__', $this->getMenus());
这个多出来的.main是个啥?新人求解答
回复讨论(解决方案)
相当于__MENU__['main'],它应该是个数组,就是你用$this->getMenus()获取到的
相当于__MENU__['main'],它应该是个数组,就是你用$this->getMenus()获取到的
对啊,是数组,那不是应该直接把数组里的挨个取出来吗?__MENU__是表示整个数组啊。
我试着这么理解您看对不对哈。
getMenus()返回的数组里面,只把键为[main]的一组进行循环赋值。
__MENU__是一个数组,__MENU__.main也就相当于__MENU__['main']
再说的明白一点,假设数组$a=array('main'=>array(1,2,3)),$a.main也就是$a['main'],也就是array(1,2,3)。
__MENU__是一个数组,__MENU__.main也就相当于__MENU__['main']
再说的明白一点,假设数组$a=array('main'=>array(1,2,3)),$a.main也就是$a['main'],也就是array(1,2,3)。
0~懂了,
那为什么不写成
assign(__MENU__,getMenus().main)
php5.4+ 可以这样
assign(__MENU__,getMenus()['main'])
若小php5.4版本
就这样
$tmp=getMenus();assign(__MENU__,$tmp['main'])

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.
