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
回复讨论(解决方案)
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
$fangxiang = array( 0 => array("fid"=>"101","Name"=>"自动化研究所","professor"=>"张教授"), 1 => array("fid"=>"102","Name"=>"实验室","professor"=>"李教授"), 2 => array("fid"=>"103","Name"=>"科学研究所","professor"=>"王教授"),);那就需要遍历了
foreach($fangxiang as $item) { if($itrm['fid'] == $id) break;}echo $item['Name'];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>
搜索的。

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.
