如何将重音符号与PHP preg匹配? [英] How do I match accented characters with PHP preg?

问题描述

我想给我的用户一个选项，它不仅可以填写字母和数字，而且可以填写á"，é"等特殊"字母.但是，我不希望他们能够使用！"，"@"，％"等符号.

I’d like to give my users the option to not only fill in letters and numbers, but also "special" letters like the "á", "é", etc. However, I do not want them to be able to use symbols like "!", "@", "%", etc.

是否可以编写正则表达式来完成此任务? (最好不指定每个特殊字母.)

Is there a way to write a regex to accomplish this? (Preferably without specifying each special letter.)

现在我有

$reg = '/^[\w\-]*$/';

推荐答案

您可以使用 Unicode字符属性描述字符:

/^[\p{L}-]*$/u

\p{L}描述Unicode字母字符的类别.

\p{L} describes the class of Unicode letter characters.
