strtr函数字符替换出现乱码
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

Dependency Injection in PHP: Code Examples for BeginnersMay 14, 2025 am 12:08 AMYou should care about DependencyInjection(DI) because it makes your code clearer and easier to maintain. 1) DI makes it more modular by decoupling classes, 2) improves the convenience of testing and code flexibility, 3) Use DI containers to manage complex dependencies, but pay attention to performance impact and circular dependencies, 4) The best practice is to rely on abstract interfaces to achieve loose coupling.

Dependency Injection vs. Service Locator in PHPMay 13, 2025 am 12:10 AMSelect DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.
