1. php中怎麼把下拉列表中的數據按字母排序，並實現拼音的搜索啊
用ajax實現
2. PHP漢字轉拼音如何把每個漢字拆分出來
使用explode就可以，例如：
<?php
$s='阿a,啊a,茬cha,茶cha,嵖cha';
foreach(explode(',',$s) as $code){
$ch=substr($code,0,2);
$code=substr($code,2);
echo "$ch\t$code<br>\n";
}
?>
3. php 如何實現拼音轉漢字請高手幫忙解答下
ecshop的拼音搜索並不是將拼音轉換成漢字進行搜索的，而是將資料庫中的數據轉換成拼音進行搜索的，將漢字轉換成拼音的php方法網上很多，隨便找一個就能用。
4. php中怎樣獲取漢字拼音的首字母
//漢字轉拼音（生僻字不支持）
$pinyin=$this->utf8_to("我是中文");
//漢字轉拼音（生僻字不支持）

}

5. php仿百度下拉拼音模糊搜索代碼
這個原理比較簡單
你在錄入每一個關鍵詞的時候，都同時錄入完整的漢語拼音
輸入時，AJAX實時進行傳遞，進行SQL的like查詢
再把結果返回給頁面，動態載入出來就好了
6. PHP中怎樣只獲取漢字
我這個測試了一下，支持GB2312編碼和UTF-8編碼，其他編碼下思路類似，只是要找下編碼的起始值就可以了。
function match_chinese($chars,$encoding='utf8'){
$pattern =($encoding=='utf8')?'/[\x{4e00}-\x{9fa5}]/u':'/[\x80-\xFF]/';
preg_match_all($pattern,$chars,$result);
$temp =join('',$result[0]);
return $temp;
}
調用：
$str ="中文漢字English Chars數字12131321";
//UTF-8編碼下
echo match_chinese($str);
//gb2312編碼下
echo match_chinese($str,'gb2312');
7. 用php怎麼取得第一個漢字的的拼音了
以前在論壇看到這么個帖子 「如何能准確獲取漢字的拼音或首字母，網上的方法都試過了」解決了我的問題。看來現在又派上又用場了。來自：php新手入門網連接： http://www.phpnewer.com/index.php/Ltqz/detail/id/45

9. php 如何把拼音轉換漢字
問題很抽象，沒有具體補充嗎？在電腦上你可以轉換一下輸入法，過去常用的拼音輸入智能abc，現在常用的搜狗輸入法，都可以將拼音轉換成漢字，只要你輸入相應的拼音，然後按數字選擇你要打的字就可以了。若是手機的話，因手機而異，不好細說，但是都不會很難，可以找親近的人研究一下
10. [轉載]PHP如何取得漢字的拼音首字母
以上函數返回單個漢字的拼音首字母，當需要處理中文字元串時，只需要重新寫一個函數，用來取得一串漢字的拼音首字母。
