PHP Chinese speech to pinyin function

PHP Chinese to pinyin function
Today, someone in Phpcms asked a question, that is, how to convert the Chinese into pinyin, this problem I was the first time to see, so Baidu a bit, found a usable function

    
 {$_q = Ord (substr ($_string, + + $i, 1)), $_p = $_p*256 + $_q-65536;               } $_res. = _pinyin ($_p, $_data);       } return Preg_replace ("/[^a-z0-9]*/", "', $_res); } function _pinyin ($_num, $_data) {if ($_num>0 && $_num<160) {retur              n Chr ($_num);              }elseif ($_num<-20319 | | $_num>-10247) {return ';                       }else{foreach ($_data as $k = $v) {if ($v <=$_num) break;}               return $k;               }} function _u2_utf8_gb ($_c) {$_string = ';              if ($_c < 0x80) {$_string. = $_c;                       }elseif ($_c < 0x800) {$_string. = Chr (0xC0 | $_c>>6);               $_string. = Chr (0x80 | $_c & 0x3F);                      }elseif ($_c < 0x10000) { $_string. = Chr (0xE0 | $_c>>12);                       $_string. = Chr (0x80 | $_c>>6 & 0x3F);               $_string. = Chr (0x80 | $_c & 0x3F);                       }elseif ($_c < 0x200000) {$_string. = Chr (0xF0 | $_c>>18);                       $_string. = Chr (0x80 | $_c>>12 & 0x3F);                       $_string. = Chr (0x80 | $_c>>6 & 0x3F);               $_string. = Chr (0x80 | $_c & 0x3F);       } return Iconv (' UTF-8 ', ' GB2312 ', $_string); }//Test echo Pinyin (' Chinese text ', ' gb2312 ');   The second parameter "1" can be arbitrarily set as UTF8 encoding?>

the output is: Zhongwenzi
