ThinkPHP的View视图里怎么切分一个字符串
<code><span class="badge">{$vo.tags}</span> </code>
{$vo.tags} 是一个a|b|c 这种形式的字符串,我要把它切分成3个字符串,用三个span显示,应该怎么写?
要查出tags字段对应的哪些值,怎么写?
显示一条数据库记录的tags字段,应该怎么写呢?
回复内容:
<code><span class="badge">{$vo.tags}</span> </code>

控制器:
<code> $str='abc|efg|hij'; $arr=explode('|',$str); $this->assign('arr',$arr); </code>
视图:
<code> <foreach name="arr" item="var"> <span>{$var}</span> </foreach> </code>
楼上写的完全正确 只是我喜欢用 foreach 比较简单, volist 中很多属性都没用过
先要在控制器处理一下吧
<code>foreach($list as $k=>$v){ $v['tags'] = explode("|",$v['tags']); }</code>
<code><volist name="vo.tags" id="sub"> <span class="badge">{$sub}</span> </volist></code>
$str='abc|efg|hij';
$arr=explode('|',$str);
$this->assign('arr',$arr);
view中:
{$sub}
数组中有几个值就生成几个span
我的意思,是说,一条数据表记录,有一个字段,叫tags,tags的内容是a|b|c|, 怎么把tags分成三个span显示在页面上?
有没有路过的高手指点下?
究竟应该怎么写?

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,

Static binding (static::) implements late static binding (LSB) in PHP, allowing calling classes to be referenced in static contexts rather than defining classes. 1) The parsing process is performed at runtime, 2) Look up the call class in the inheritance relationship, 3) It may bring performance overhead.

What are the magic methods of PHP? PHP's magic methods include: 1.\_\_construct, used to initialize objects; 2.\_\_destruct, used to clean up resources; 3.\_\_call, handle non-existent method calls; 4.\_\_get, implement dynamic attribute access; 5.\_\_set, implement dynamic attribute settings. These methods are automatically called in certain situations, improving code flexibility and efficiency.

PHP and Python each have their own advantages, and choose according to project requirements. 1.PHP is suitable for web development, especially for rapid development and maintenance of websites. 2. Python is suitable for data science, machine learning and artificial intelligence, with concise syntax and suitable for beginners.

PHP is widely used in e-commerce, content management systems and API development. 1) E-commerce: used for shopping cart function and payment processing. 2) Content management system: used for dynamic content generation and user management. 3) API development: used for RESTful API development and API security. Through performance optimization and best practices, the efficiency and maintainability of PHP applications are improved.

PHP is a scripting language widely used on the server side, especially suitable for web development. 1.PHP can embed HTML, process HTTP requests and responses, and supports a variety of databases. 2.PHP is used to generate dynamic web content, process form data, access databases, etc., with strong community support and open source resources. 3. PHP is an interpreted language, and the execution process includes lexical analysis, grammatical analysis, compilation and execution. 4.PHP can be combined with MySQL for advanced applications such as user registration systems. 5. When debugging PHP, you can use functions such as error_reporting() and var_dump(). 6. Optimize PHP code to use caching mechanisms, optimize database queries and use built-in functions. 7

In PHP8, match expressions are a new control structure that returns different results based on the value of the expression. 1) It is similar to a switch statement, but returns a value instead of an execution statement block. 2) The match expression is strictly compared (===), which improves security. 3) It avoids possible break omissions in switch statements and enhances the simplicity and readability of the code.

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.
