php將名字按首字母進行排序，具體代碼如下所示：
<?php
public function getFirstChar($s){
$s0 = mb_substr($s,0,3); //獲取名字的姓
$s = iconv('UTF-8','gb2312', $s0); //將UTF-8轉換成GB2312編碼
//dump($s0);
if (ord($s0)>128) { //漢字開頭，漢字沒有以U、V開頭的
$asc=ord($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 $asc<=-17760)return "G";
if($asc>=-17759 and $asc<=-17248)return "H";
if($asc>=-17247 and $asc<=-17418)return "I";
if($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 $asc<=-10247)return "Z";
}else if(ord($s)>=48 and ord($s)<=57){ //數字開頭
switch(iconv_substr($s,0,1,'utf-8')){
case 1:return "Y";
case 2:return "E";
case 3:return "S";
case 4:return "S";
case 5:return "W";
case 6:return "L";
case 7:return "Q";
case 8:return "B";
case 9:return "J";
case 0:return "L";
}
}else if(ord($s)>=65 and ord($s)<=90){ //大寫英文開頭
return substr($s,0,1);
}else if(ord($s)>=97 and ord($s)<=122){ //小寫英文開頭
return strtoupper(substr($s,0,1));
}
else
{
return iconv_substr($s0,0,1,'utf-8');
//中英混合的詞語，不適合上面的各種情況，因此直接提取首個字符即可
}
}
public function addPeople()
{
$userName = array('張三','馬大帥','李四','王五','小二','貓蛋','狗蛋','王花','三毛','小明','李剛','張飛');
sort($userName);
foreach($userName as $name){
$char = $this->getFirstChar($name);
$nameArray = array();
if(count($charArray[$char])!=0){
$nameArray = $charArray[$char];
}
array_push($nameArray,$name);
$charArray[$char] = $nameArray;
}
ksort($charArray);
$this->assign('_list',$charArray);
}
頁面顯示
<foreach name="_list" item="vo" key="k">
<p>{$k}</p>
<foreach name="vo" item="l">
<span class="name">{$l}</span>
</foreach>
</foreach>
