We often see some websites sorted by city name or ranked by letters. Let me introduce how to implement this. Let's share a paragraph that uses PHP to obtain the first letter of a Chinese character in a Chinese string.

Example

The code is as follows

代码如下

例

$limit = array( //gb2312 拼音排序
array(45217,45252), //A
array(45253,45760), //B

array(54481,55289), //Z
);

$str="A:这是一个测试程序1";
$str= iconv("UTF-8","gb2312", $str);
echo $str."
";
$i=0;
while($i $tmp=bin2hex(substr($str,$i,1));
if($tmp>='B0'){ //汉字的开始
        $t=getLetter(hexdec(bin2hex(substr($str,$i,2))));
        printf("%c",$t==-1 ? '*' : $t );
        $i+=2;
    }
    else{
        printf("%s",substr($str,$i,1));
        $i++;
    }
}

function getLetter($num){
    global $limit;
    $char_index=65;
    foreach($limit as $k=>$v){
        if($num>=$v[0] && $num<=$v[1]){
$char_index+=$k;
return $char_index;
}
}
return -1;
}
?>
