在处理csv文件导入时关于fgetcsv获取中文乱码问题.. 因为项目采用utf-8编码, 而导入的csv文件是以ansi编码保存的  输出中文乱码问题.

下面为找到的解决方法原文.

今天在处理csv文件导入的时候,通过fgetcsv方法返回的数组中,值为汉字的部分全是乱码。我分析是因为项目的文件全部以utf-8编码,而
导入的csv文件是以ansi编码保存的,对于中文操作系统环境对应的应该就是gbk编码了,通过手动更改浏览器字符编码为gbk,乱码的情况消失了。于
是决定对数组进行编码转换。

系统默认的编码转换函数iconv只能接受字符串参数,当然我们可以通过array_walk……等数组方法利用回调函数递归的来进行处理,也可以
直接读取数组单元处理后再填入数组。但是感觉数组如果很庞大或者维数过多,性能上的比较就不得不考虑了。正因为iconv函数只能接受字符串参数,于是想
到将数组先利用函数serialize序列化,通过iconv转换编码后再用unserialize反序列化回来。但不知道为什么转换编码后无法反序列化
回来,找个时间单独实验一下,清楚的朋友给我留个言也好。

于是求助其他Variable handling
函数。在这里var_export函数可以输出或返回一个变量的字符串表示。此函数返回关于传递给该函数的变量的结构信息,它和 var_dump()
类似,不同的是其返回的表示是合法的 PHP 代码。可以通过将函数的第二个参数设置为 TRUE,从而返回变量的表示。下面就利用这一特性将数组转化为字符串然后再iconv接着再用eval函数将其还原为数组。这次结果正确显示了。

<span style="color: rgb(102, 102, 153);">$data</span> = <span style="color: rgb(51, 102, 255);">eval</span>('return '.<span style="color: rgb(51, 102, 255);">iconv</span>('gbk','utf-8',<span style="color: rgb(51, 102, 255);">var_export</span>($data,true)).';');
Copy after login

$data为需要转换编码的数组。

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,

Explain the match expression (PHP 8 ) and how it differs from switch. Explain the match expression (PHP 8 ) and how it differs from switch. Apr 06, 2025 am 12:03 AM

In PHP8, match expressions are a new control structure that returns different results based on the value of the expression. 1) It is similar to a switch statement, but returns a value instead of an execution statement block. 2) The match expression is strictly compared (===), which improves security. 3) It avoids possible break omissions in switch statements and enhances the simplicity and readability of the code.
