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); }
