php将名字按首字母进行排序&＃xff0c;具体代码如下所示&＃xff1a;

public function getFirstChar($s){

$s0 &＃61; mb_substr($s,0,3); //获取名字的姓

$s &＃61; iconv(&＃39;UTF-8&＃39;,&＃39;gb2312&＃39;, $s0); //将UTF-8转换成GB2312编码

//dump($s0);

if (ord($s0)>128) { //汉字开头&＃xff0c;汉字没有以U、V开头的

$asc&＃61;ord($s{0})*256&＃43;ord($s{1})-65536;

if($asc>&＃61;-20319 and $asc<&＃61;-20284)return "A";

case 4:return "S";

case 0:return "L";

}

}else if(ord($s)>&＃61;65 and ord($s)<&＃61;90){ //大写英文开头

return substr($s,0,1);

}else if(ord($s)>&＃61;97 and ord($s)<&＃61;122){ //小写英文开头

return strtoupper(substr($s,0,1));

}

else

{

return iconv_substr($s0,0,1,&＃39;utf-8&＃39;);

//中英混合的词语&＃xff0c;不适合上面的各种情况&＃xff0c;因此直接提取首个字符即可

}

}

public function addPeople()

{

$userName &＃61; array(&＃39;张三&＃39;,&＃39;马大帅&＃39;,&＃39;李四&＃39;,&＃39;王五&＃39;,&＃39;小二&＃39;,&＃39;猫蛋&＃39;,&＃39;狗蛋&＃39;,&＃39;王花&＃39;,&＃39;三毛&＃39;,&＃39;小明&＃39;,&＃39;李刚&＃39;,&＃39;张飞&＃39;);
