这篇文章主要介绍了php实现姓名根据首字母排序的类与方法,代码简单易懂,非常不错,具有一定的参考借鉴价值,需要的朋友参考下吧。
php将名字按首字母进行排序,具体代码如下所示:
- <?php
- public function getFirstChar($s){
- $s0 = mb_substr($s,0,3); //获取名字的姓
- $s = iconv('UTF-8','gb2312', $s0); //将UTF-8转换成GB2312编码
- //dump($s0);
- if (ord($s0)>128) { //汉字开头,汉字没有以U、V开头的
- $asc=ord($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($s)<=57){ //数字开头
- switch(iconv_substr($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){ //大写英文开头
- return substr($s,0,1);
- }else if(ord($s)>=97 and ord($s)<=122){ //小写英文开头
- return strtoupper(substr($s,0,1));
- }
- else
- {
- return iconv_substr($s0,0,1,'utf-8');
- //中英混合的词语,不适合上面的各种情况,因此直接提取首个字符即可
- }
- }
- public function addPeople()
- {
- $userName = array('张三','马大帅','李四','王五','小二','猫蛋','狗蛋','王花','三毛','小明','李刚','张飞');
- sort($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);
- }
页面显示
- <foreach name="_list" item="vo" key="k">
- <p>{$k}</p>
- <foreach name="vo" item="l">
- <span class="name">{$l}</span>
- </foreach>
- </foreach>
