PHP正则表达式验证字母和西班牙语口音 [英] PHP Regex validate letters and Spanish accent

问题描述

我如何添加/即兴我的代码，所以除了正常的字母（az）之外，西班牙语将被视为有效。

How can I add/improvised my code so Spanish accent will be considered as valid in addition to normal alphabet (a-z)

我的代码中有以下内容

public static function IsAlpha($s){
  $reg = "#[^a-z\s-]#i";
  $count = preg_match($reg, $s, $matches);
  return $count == 0;
}

推荐答案

此问题，您可以匹配重音字符使用完整的信 Unicode属性 \p {L} 。这包括常规的 az 字符和重音符，所以用这样替换你的表达式中的 az ：

As found in the answer to this question, you could match accented characters using the full Letter Unicode property \p{L}. That includes regular a-z characters along with accented ones, so replace a-z in your expression with this like so:

$reg = "#[^\p{L}\s-]#u";

请注意，要使用这个，您需要 UTF-8修饰符 u 在您的关闭分隔符后，作为当选择 UTF-8模式 时，docs会显示这样的Unicode字符类型。

Note that to use this you need the UTF-8 modifier u after your closing delimiter, as the docs say such Unicode "character types are available when UTF-8 mode is selected".
