推荐答案

正如@deceze所写，您需要使用 mb_substr 以获得字符，而不只是一个字节.另外，您需要使用 mb_internal_encoding 设置内部编码.假设您的.php文件的编码为UTF-8，则应该可以进行以下操作:

As @deceze writes, you need to use mb_substr in order to get a character, instead of just a byte. In addition, you need to set the internal encoding with mb_internal_encoding. Assuming that the encoding of your .php file is UTF-8, the following should work:

  mb_internal_encoding('utf-8');
  $str = "पर्वत निर्माणों में कोनसा संचलन कार्य करता है"; 
  echo mb_substr($str, 0, 1);
