在PHP中检测非字母语言字符串 [英] Detect non-alphabetic language string in PHP

问题描述

我对此有一个类似的问题一个

I have a similar question to this one

但是，我的要求不太严格.

However, I have a less strict requirement.

我需要做的就是检测输入字符串是否包含任何非字母字符串.

All I need is to detect if the input string contains any non alphabetic string.

如果它确实包含非字母字符串，那么我将选择其他字体文件.

If it does contain non-alphabetic string, then I will select a different font file.

如果它仅包含字母字符串，那么我将选择一个字体文件，例如AmericanTypeWriter.

if it contains ONLY alphabetic string, then I will select a font file like AmericanTypeWriter.

通过字母字符串，其中包括各种可能的符号，例如逗号，标点符号等.

很难定义字母字符串.

让我定义什么是非字母字符串的例子.

Let me define what is an example of non-alphabetic string.

这是中文

并假定字符串为utf-8格式.

And assuming utf-8 format for the string.

另一种定义方式:任何不属于非欧洲语言字符的内容，都会自动假定为字母字符串.

我需要在php中进行此检测.

I need to do this detection in php by the way.

I found a better answer. Inspired by https://stackoverflow.com/a/4923410/80353

header('Content-Type: text/html; charset=utf-8');
mb_internal_encoding('utf-8');

function isThisChineseText($text) {
    return preg_match("/\p{Han}+/u", $text);
}
