emoji 表情是扩展的 utf-16 编码
你可以贴出含有 emoji表情 的文字的 base64 编码串
看看能否帮你解决问题

这个就是表情base64位保存后的数据。8J+YhPCfmIM= 。版*烦看看!.现在好多应用都支持这个表情输入,就是不知道怎么保存的。

应该说改用 utf8mb4 字符集就可以了,不知道你为什么不行
考虑到文字中 emoji 字符并不多,可以用正则替换一下在存入

$text = base64_decode('8J+YhPCfmIM=');echo $text = preg_replace_callback('/[\xf0-\xf7].{3}/', function($r) { return '@E' . base64_encode($r[0]);}, $text);
Copy after login
Copy after login
@E8J+YhA==@E8J+Ygw==

都会后逆转换一下就可以了
$s = preg_replace_callback('/@E(.{6}==)/', function($r) {return base64_decode($r[1]);}, '@E8J+YhA==@E8J+Ygw==');var_dump(base64_decode('8J+YhPCfmIM=') == $s);
Copy after login
Copy after login
bool(true)

是啊,很郁闷。网上都说只要设置为utf8mb4 就行,可我的就不行。mysql的版本是用的是5.6的。。。。,wampserver环境。会不会是环境问题?

楼主,我也遇到相同的问题了,请问你最后怎么解决的?

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,

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.
