You could use a unicode character class http://www.regular-expressions.info/unicode.html
您可以使用 unicode 字符类http://www.regular-expressions.info/unicode.html
preg_match("/\p{Han}+/u", $utf8_str);
This just checks for the presence of at least one chinese character. You might want to expand on this if you want to match the complete string.
这只是检查是否存在至少一个汉字。如果您想匹配完整的字符串，您可能需要对此进行扩展。

preg_match("/^\p{Han}{2,10}+$/u", $str);
Use /^\p{Han}{2,10}+$/uregex which allows Chinese character only.
使用/^\p{Han}{2,10}+$/u正则表达式，只允许汉字。
- It allows chinese character only &
- It allows Minimum 2 character &
- It allows maximum 10 character
- 它只允许汉字 &
- 它允许至少 2 个字符 &
- 它允许最多 10 个字符
You can change minimum and maximum character by changing {2,10} as per your need.
您可以根据需要通过更改 {2,10} 来更改最小和最大字符。
\p& /uare very important to add please don't avoid to add it.
\p& /u添加非常重要，请不要避免添加。
