<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:

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?

What’s still popular is the ease of use, flexibility and a strong ecosystem. 1) Ease of use and simple syntax make it the first choice for beginners. 2) Closely integrated with web development, excellent interaction with HTTP requests and database. 3) The huge ecosystem provides a wealth of tools and libraries. 4) Active community and open source nature adapts them to new needs and technology trends.

PHP and Python are both high-level programming languages that are widely used in web development, data processing and automation tasks. 1.PHP is often used to build dynamic websites and content management systems, while Python is often used to build web frameworks and data science. 2.PHP uses echo to output content, Python uses print. 3. Both support object-oriented programming, but the syntax and keywords are different. 4. PHP supports weak type conversion, while Python is more stringent. 5. PHP performance optimization includes using OPcache and asynchronous programming, while Python uses cProfile and asynchronous programming.

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.

PHP originated in 1994 and was developed by RasmusLerdorf. It was originally used to track website visitors and gradually evolved into a server-side scripting language and was widely used in web development. Python was developed by Guidovan Rossum in the late 1980s and was first released in 1991. It emphasizes code readability and simplicity, and is suitable for scientific computing, data analysis and other fields.

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.

PHP remains important in the modernization process because it supports a large number of websites and applications and adapts to development needs through frameworks. 1.PHP7 improves performance and introduces new features. 2. Modern frameworks such as Laravel, Symfony and CodeIgniter simplify development and improve code quality. 3. Performance optimization and best practices further improve application efficiency.

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.
