php漢字轉(zhuǎn)首字母大寫的實(shí)現(xiàn)方法：首先創(chuàng)建一個(gè)PHP示例文件；然后定義一個(gè)“getfirstchar”方法用于獲取漢字拼音且將首字母轉(zhuǎn)為大寫；最后通過echo輸出轉(zhuǎn)換結(jié)果即可。

PHP 獲取漢字拼音首字母大寫

<?php   function getfirstchar($s0) {     $fchar = ord(substr($s0, 0, 1));     if (($fchar >= ord("a") and $fchar <= ord("z"))or($fchar >= ord("A") and $fchar <= ord("Z"))) return strtoupper(chr($fchar));     $s = iconv("UTF-8", "GBK", $s0);     $asc = ord($s{0}) * 256 + ord($s{1})-65536;     if ($asc >= -20319 and $asc <= -20284)return "A";     if ($asc >= -20283 and $asc <= -19776)return "B";     if ($asc >= -19775 and $asc <= -19219)return "C";     if ($asc >= -19218 and $asc <= -18711)return "D";     if ($asc >= -18710 and $asc <= -18527)return "E";     if ($asc >= -18526 and $asc <= -18240)return "F";     if ($asc >= -18239 and $asc <= -17923)return "G";     if ($asc >= -17922 and $asc <= -17418)return "H";     if ($asc >= -17417 and $asc <= -16475)return "J";     if ($asc >= -16474 and $asc <= -16213)return "K";     if ($asc >= -16212 and $asc <= -15641)return "L";     if ($asc >= -15640 and $asc <= -15166)return "M";     if ($asc >= -15165 and $asc <= -14923)return "N";     if ($asc >= -14922 and $asc <= -14915)return "O";     if ($asc >= -14914 and $asc <= -14631)return "P";     if ($asc >= -14630 and $asc <= -14150)return "Q";     if ($asc >= -14149 and $asc <= -14091)return "R";     if ($asc >= -14090 and $asc <= -13319)return "S";     if ($asc >= -13318 and $asc <= -12839)return "T";     if ($asc >= -12838 and $asc <= -12557)return "W";     if ($asc >= -12556 and $asc <= -11848)return "X";     if ($asc >= -11847 and $asc <= -11056)return "Y";     if ($asc >= -11055 and $asc <= -10247)return "Z";     return null; }   function mb_str_split($string) {     return preg_split('/(?<!^)(?!$)/u', $string); }   function get_letter($string) {     $charlist = mb_str_split($string);     return implode(array_map("getfirstchar", $charlist)); } echo get_letter("剎車片"); ?>

結(jié)果：
