PHP Chinese to pinyin function

PHP Chinese to pinyin function
Just found a very useful function in the blog park, you can turn the Chinese into pinyin, reproduced

 {$_q = Ord (substr ($_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 && $_num<160) {return Chr ($_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 | $_c &Amp         0x3F);                 }elseif ($_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?>
