一系列 unicode 点 PHP 的正则表达式

您可以使用：

$foo = preg_replace('/[^\w$\x{0080}-\x{FFFF}]+/u', '', $foo);

• \w- 等价于[a-zA-Z0-9_]
• \x{0080}-\x{FFFF}在码位 +0080U+FFFF' 之间匹配字符Uand
• /u用于正则表达式中的 unicode 支持

现代化的答案。

如果 Unicode 范围扩展到 U+10FFFF
，那么仅仅排除代码点 U+80 - U+FFFF 是不明智的。

如今，这涵盖了超过16位bmp范围的许多字符。

我将向您展示如何在 utf-16 或
utf-8/32 中以您想要的范围内执行此操作，您可能控制也可能无法控制。

UTF-16

 # UTF-16 regex ;   equavelent UTF-8/32 regex   (?![\x{80}-\x{FFFF}])[$\w]

 (?!
      (?:
           [\x{80}-\x{D7FF}\x{E000}-\x{FFFF}] 
        |  
           [\x{D800}-\x{DBFF}] 
           (?! [\x{DC00}-\x{DFFF}] )
        |  
           [\x{DC00}-\x{DFFF}] 
           (?<! [\x{D800}-\x{DBFF}] [\S\s] )
      )

最后，最简单的是将范围扩展到U + 10FFFF

 # UTF-8/32 regex ;

 (?! [\x{80}-\x{10FFFF}] )
 [$\w] 


 # Output --------------------------------
 # 64 Unicode characters
 # UTF-8 / 16/ 32 regex equivalent (using codepoints)

 [\x{24}\x{30}-\x{39}\x{41}-\x{5A}\x{5F}\x{61}-\x{7A}] 

 # Codepoint -> character substitution
