php 问卷调查结果统计_php实例
背景:
由于具体工作的原因,我做了一份纸质的问卷调查表,调查表的主要内容是让用户对项要求(编号为A,B....)进行优先级排序,所以我得到的结果是好几百份类似于A>I>H>G>D....等结果。
目标:
根据用户的排序结果对这项要求进行量化考评,最终的结果希望是A:,B:,C:.....,以找出哪一个要素相对重要,而另一些相对不重要。
做法:
根据编号的排位名次,赋与不一样的权重,统计所有的结果,将这些权重汇总。例如:“ABCDEFGHIJ”这个结果表示A这一项得到分,J这项得到了分,D这项得到了分。
知识点:
文件读取;循环;关联数组;数组排序。
php代码:
$rs =array("A"=>,"B"=>,"C"=>,"D"=>,"E"=>,"F"=>,"G"=>,"H"=>,"I"=>,"J"=>); $handle = fopen('./file.txt', 'r'); while(!feof($handle)) { $string = fgets($handle, ); for($i=;$i<strlen($string);$i++) { $t = strtoupper($string[$i]); if(isset($rs[$t])) $rs[$t] = $rs[$t]+ strlen($string) - $i; } } fclose($handle); arsort($rs); var_dump($rs);
说明:file.txt是一个文本文件,其中的每一行表示一份问卷的结果,类似于“ABCDEFGHIJ”这样的东西。这个文件是如何得到了呢?好吧,我承认不是我自己手动录入的,我找了些人帮忙(为什么不做网上问卷呢?省得这么麻烦)
以上内容就是本文给大家介绍的php 问卷调查结果统计,希望对大家有所帮助。

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,

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.

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.

The enumeration function in PHP8.1 enhances the clarity and type safety of the code by defining named constants. 1) Enumerations can be integers, strings or objects, improving code readability and type safety. 2) Enumeration is based on class and supports object-oriented features such as traversal and reflection. 3) Enumeration can be used for comparison and assignment to ensure type safety. 4) Enumeration supports adding methods to implement complex logic. 5) Strict type checking and error handling can avoid common errors. 6) Enumeration reduces magic value and improves maintainability, but pay attention to performance optimization.
