In PHP development, we often encounter the problem of Chinese displaying garbled characters, especially During data reading, storage and display. This kind of problem makes web content difficult to understand, affecting user experience and information transmission. How to solve the problem of Chinese display garbled characters in PHP web pages has become one of the technical challenges that developers need to focus on. This article will provide specific methods and code examples on how to effectively solve the problem of Chinese display garbled characters in PHP web pages.

Common Chinese display garbled problems mainly include the following situations:

1. Database storage problem: When Chinese data is stored in the database, if the encoding format of the table fields in the database is different from If the encoding format of Chinese data is inconsistent, garbled characters will occur.
