输出 \ud83d\udc38
那么 问题来了!!!
\ud83d\udc38
应该经过怎样的处理得到 🐸
下面是我写的处理,但是不能输出我想要的数值,iconv("UCS-2","UTF-8",pack("H4","\\1")) 不起作用有时得到乱码。
<code>$str=preg_replace('#(\\\u[0-9a-f]{4}\\\u[0-9a-f]{4})#ie','iconv("UCS-2","UTF-8",pack("H4","\\1"))',$str);</code>
更改mysql的数据类型这个方案不能考虑
我完整的需求是这样的:
1、我输入一段话 例如 “一二三四五上山打老虎?”,我在保存进mysql时,需要将?转换成能写进mysql的编码,但是“一二三四五上山打老虎”这部分我需要原文存进数据库,这里就需要对输入的文本进行的正则过滤,然后将?转码,其他正常符号中英文不转码。
2、从数据库输出数据时,我用正则匹配出?的转码,将其输出为?和(🐸
或0x1f438
),因为我在前端显示的静态的图片表示?,图片的来源于twitter的emoji库,图片的名称就是以1f438
命名的。
完整的需求就是这样的。求大神指点下。

? 的unicode 是 0x1f438,无法用两字节的 UCS-2 编码,用 UCS-4 可以。
大概是这么个思路:
<code><?php function uniord($u) { $k = mb_convert_encoding($u, 'UCS-4LE', 'UTF-8'); $k1 = ord(substr($k, 0, 1)); $k2 = ord(substr($k, 1, 1)); $k3 = ord(substr($k, 2, 1)); return $k3 * 256 * 256 + $k2 * 256 + $k1; } echo uniord('?');</code></code>
用mb,
iconv纯属扯淡
在线等 哼哼

Select 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.

Dependency injection (DI) significantly improves the testability of PHP code by explicitly transitive dependencies. 1) DI decoupling classes and specific implementations make testing and maintenance more flexible. 2) Among the three types, the constructor injects explicit expression dependencies to keep the state consistent. 3) Use DI containers to manage complex dependencies to improve code quality and development efficiency.
