php二维数组的问题,求大神解答

Jun 23, 2016 pm 01:45 PM

我现在有个页面searchFangxiang.php定义了一个二维数组:
$fangxiang=array('fid101'=>array("fid"=>"101","Name"=>"自动化研究所","professor"=>"张教授"),
                                      'fid102'=>array("fid"=>"102","Name"=>"实验室","professor"=>"李教授"),
                  'fid103'=>array("fid"=>"103","Name"=>"科学研究所","professor"=>"王教授")););
 
?>

然后在我的应用页面引用了这个二维数组的页面


include 'searchFangxiang.php';

echo  "";
?>

现在应用页面有个 id   我如何遍历这个二维数组,找到二维数组中 fid与页面id相同的那一组,然后在标签中输出这一组的信息

按你的数据组织方式,不需要遍历
只需 echo $fangxiang ["fid$id"]['Name']; 即可

转成json放到应用页面,通过js或jquery处理读取

按你的数据组织方式,不需要遍历
只需 echo $fangxiang ["fid$id"]['Name']; 即可


是哦,想复杂了。。。


按你的数据组织方式,不需要遍历
只需 echo $fangxiang ["fid$id"]['Name']; 即可



我这也太新手了,  我还在循环判断呢

如果不是这样组织的

$fangxiang = array(  'fid101' => array("fid"=>"101","Name"=>"自动化研究所","professor"=>"张教授"),  'fid102' => array("fid"=>"102","Name"=>"实验室","professor"=>"李教授"),  'fid103' => array("fid"=>"103","Name"=>"科学研究所","professor"=>"王教授"),);

而是这样组织的
$fangxiang = array(  0 => array("fid"=>"101","Name"=>"自动化研究所","professor"=>"张教授"),  1 => array("fid"=>"102","Name"=>"实验室","professor"=>"李教授"),  2 => array("fid"=>"103","Name"=>"科学研究所","professor"=>"王教授"),);
Copy after login
Copy after login
那就需要遍历了
foreach($fangxiang as $item) {  if($itrm['fid'] == $id) break;}echo $item['Name']; 
Copy after login
Copy after login
可见合适的数据结构可以带来事半功倍的效果

大神 我还有一个问题,我现在要在页面上做个搜索的功能,怎样写模糊查找啊,比如我搜索 “科学”,就把Name中带科学两个字
的这一组信息查出来,搜索名字也一样,php能办到这点不

这种效果要用 js 完成

<?php$fangxiang=array('fid101'=>array("fid"=>"101","Name"=>"自动化研究所","professor"=>"张教授"),                 'fid102'=>array("fid"=>"102","Name"=>"实验室","professor"=>"李教授"),                 'fid103'=>array("fid"=>"103","Name"=>"科学研究所","professor"=>"王教授")); $id = 101;?><meta http-equiv="content-type" content="text/html; charset=utf-8"><div class="news_title_01_box"><?phpecho  "<span class='news_title_01'>".$fangxiang['fid'.$id]["Name"]."</span>";?></div>
Copy after login

搜索的。

Explain JSON Web Tokens (JWT) and their use case in PHP APIs. Explain JSON Web Tokens (JWT) and their use case in PHP APIs. Apr 05, 2025 am 12:04 AM

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,

How does session hijacking work and how can you mitigate it in PHP? How does session hijacking work and how can you mitigate it in PHP? Apr 06, 2025 am 12:02 AM

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.

Describe the SOLID principles and how they apply to PHP development. Describe the SOLID principles and how they apply to PHP development. Apr 03, 2025 am 12:04 AM

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.

Explain late static binding in PHP (static::). Explain late static binding in PHP (static::). Apr 03, 2025 am 12:04 AM

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.
