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'])

In PHP, password_hash and password_verify functions should be used to implement secure password hashing, and MD5 or SHA1 should not be used. 1) password_hash generates a hash containing salt values to enhance security. 2) Password_verify verify password and ensure security by comparing hash values. 3) MD5 and SHA1 are vulnerable and lack salt values, and are not suitable for modern password security.

PHP type prompts to improve code quality and readability. 1) Scalar type tips: Since PHP7.0, basic data types are allowed to be specified in function parameters, such as int, float, etc. 2) Return type prompt: Ensure the consistency of the function return value type. 3) Union type prompt: Since PHP8.0, multiple types are allowed to be specified in function parameters or return values. 4) Nullable type prompt: Allows to include null values and handle functions that may return null values.

PHP is mainly procedural programming, but also supports object-oriented programming (OOP); Python supports a variety of paradigms, including OOP, functional and procedural programming. PHP is suitable for web development, and Python is suitable for a variety of applications such as data analysis and machine learning.

Using preprocessing statements and PDO in PHP can effectively prevent SQL injection attacks. 1) Use PDO to connect to the database and set the error mode. 2) Create preprocessing statements through the prepare method and pass data using placeholders and execute methods. 3) Process query results and ensure the security and performance of the code.

PHP and Python have their own advantages and disadvantages, and the choice depends on project needs and personal preferences. 1.PHP is suitable for rapid development and maintenance of large-scale web applications. 2. Python dominates the field of data science and machine learning.

PHP uses MySQLi and PDO extensions to interact in database operations and server-side logic processing, and processes server-side logic through functions such as session management. 1) Use MySQLi or PDO to connect to the database and execute SQL queries. 2) Handle HTTP requests and user status through session management and other functions. 3) Use transactions to ensure the atomicity of database operations. 4) Prevent SQL injection, use exception handling and closing connections for debugging. 5) Optimize performance through indexing and cache, write highly readable code and perform error handling.

PHP is used to build dynamic websites, and its core functions include: 1. Generate dynamic content and generate web pages in real time by connecting with the database; 2. Process user interaction and form submissions, verify inputs and respond to operations; 3. Manage sessions and user authentication to provide a personalized experience; 4. Optimize performance and follow best practices to improve website efficiency and security.

PHP is suitable for web development and rapid prototyping, and Python is suitable for data science and machine learning. 1.PHP is used for dynamic web development, with simple syntax and suitable for rapid development. 2. Python has concise syntax, is suitable for multiple fields, and has a strong library ecosystem.
