如何与正则表达式匹配除“-"以外的所有特殊字符在PHP中?

问题描述

我如何匹配PHP中除char -之外的所有特殊"字符(如+_*&^%$#@!~)?

How can I match all the "special" chars (like +_*&^%$#@!~) except the char - in PHP?

我知道\W会匹配包括-在内的所有特殊"字符.

I know that \W will match all the "special" chars including the -.

关于Unicode字母的任何建议吗?

Any suggestions in consideration of Unicode letters?

推荐答案

• [^-]不是您想要的特殊字符
• [\W]都是已知的特殊字符
• [^\w]都是特殊字符-听起来还不错吗?
• [^-] is not the special character you want
• [\W] are all special characters as you know
• [^\w] are all special characters as well - sounds fair?

因此，[^\w-]是两者的组合:所有特殊"字符，但没有-.

So therefore [^\w-] is the combination of both: All "special" characters but without -.
