strtr函数字符替换出现乱码

Jun 23, 2016 pm 02:18 PM

我的替换词库来源于一个文本文件。文本文件无论改成gbk还是utf-8格式都出现乱码。
如果把替换词库自己定义如下:
$words = array('发文说'=>'DDDDDDDDDDDDDDDDDDDd');
替换就不会出现乱码
$data['content'] = strtr($data['content'], $words);

我把words变量打印出来,里面的词组都没有乱码,用函数检测,也不是utf-8格式。所以可以确认,内容和替换词组都是gbk格式的字符串。
请问如何解决这个问题?谢谢

你词库的格式?你如何读词库的?

你词库的格式?你如何读词库的?

$data_file = PICK_DATA.'/word.txt';$handle = fopen($data_file, "r");$data = fread($handle, filesize($data_file));
Copy after login

你词库的格式?你如何读词库的?

我在网上搜索,得到答案说: 因为strtr在字符串替换的时候是以单个字节对应进行替换的,所以对于非单字节编码的数据(如中文utf-8)就可以会出现乱码。
但是我的字符串都是gbk呀。而且我以前也用这个函数,没出现乱码。到这里就出现乱码了,不知道为何。

你没有说你的词库是如何组织的

不多只要你的原词有单个汉字的话,乱码的概率一般不会低于50%

问题找到了。我切割字符的时候用的是\n,而不是\r\n。这就是造成乱码的原因。感谢回答。

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

What are Enumerations (Enums) in PHP 8.1? What are Enumerations (Enums) in PHP 8.1? Apr 03, 2025 am 12:05 AM

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.

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.
