foreach循环中,这样的变化如何写
输出的内容一样的,只是样式不一样,
第一个输出
题目1
第二个输出
题目2|(没有标签了且后面跟有|)
以此类推
我只写出了第一个,第二个不会写了,我也知道要用判断,但不知怎么写
<?php if(!empty($output['navigation_list']) && is_array($output['navigation_list'])) {?> <?php foreach($output['navigation_list'] as $value) {?> <?php if($value['navigation_id']>11 && $value['navigation_id']<27){?> <strong><a href="#">题目1</a></strong> <?php } ?> <?php } ?> <?php } ?>

你没说清变化的规则是什么啊。
你没说清变化的规则是什么啊。
就是隔一行输出一个,比如
第一行,输出它 题目1
第二行,输出它题目2|
然后第三行再输出第一次这个样式题目1
第四行再输出第二行的样式题目2|,
第五行再重复第输出第一次的样式,第六行再输出第二次的样式,以此类推,循环起来。。…。………明白了吧
可以简单的参考下:
$array = array(1,2,3,4,5,6,7,8,9,10); $num=1; foreach ($array as $key => $value) { if($num%2==0){ echo '<strong><a href="#">题目'.$value.'</a></strong><span>|</span>'; }else{ echo '<strong><a href="#">题目'.$value.'</a></strong> '; } $num++; }

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.
