用excel读取csv文件中的阿拉伯文时出错

Question

我有这段代码将数据库表格导出为csv，我拥有这样的代码，它应该看起来像这样的علي。我不知道是什么问题，是因为编码还是什么。我的表归类为utf8_general_ci

$mysqli = new mysqli('localhost', 'root', '', 'test'); 
if ($mysqli->connect_errno) 
{ 
$debug = $debug.'<br/>Failed to connect to MySQL: (' . $mysqli->connect_errno . ') ' . $mysqli->connect_error; 
    } 
else 
{ 
$debug = $debug.'<br/>Connected to '. $mysqli->host_info; 
} 

function export($query_exp,$name) 
{ 
require 'classs.php'; 

$filename = $name.' - '.date('Y.m.d').'.xls'; /*set desired output file name here*/ 

function cleanData(&$str) 
      { 
       $str = preg_replace("/\t/", "\\t", $str); 
       $str = preg_replace("/\r?\n/", "\\n", $str); 
       if(strstr($str, '"')) $str = '"' . str_replace('"', '""', $str) . '"'; 
       if ($str=='') {$str='-';} 
      } 

header("Content-Disposition: attachment; filename=\"$filename\""); 
header("Content-Type: application/vnd.ms-excel"); 

$flag = false; 

if ($result = $mysqli->query($query_exp)) 
     { 
     if ($result->num_rows>0) 
      { 
      $result->data_seek(0); 
      while ($row = $result->fetch_assoc()) 
       { 
       if(!$flag) 
        { 
        print implode("\t", array_keys($row)) . "\r\n"; 
        $flag = true; 
        } 
       array_walk($row, 'cleanData'); 
       print implode("\t", array_values($row)) . "\r\n"; 
       } 
      } 
     else { $debug = $debug.'<br/>Empty result'; /*DEBUG*/ } 
     } 
else { $debug = $debug.'<br/>Oups, Query error!<br/>Query: '.$query_exp.'<br/>Error: '.$mysqli->error.'.'; /*DEBUG*/ } 

require 'classs.php'; 
} 
export('SELECT * FROM exel;','file');

连接后，你需要告诉您要发送的MySQL，并希望得到UTF8：

$mysql->query("set names 'utf-8'");
