使用php将MySQL表导出到excel。 编码问题

Question

I try to export one of MySQL table into excel file but polish letters aren't displaying correctly It is displayed: Bre¶ć, Białoru¶ but should: Brześć, Białoruś

How can I fix this code? It is really anoying that polish letters aren't displayed. Where could be a problem?

<?php

 $DB_Server = "localhost";      //your MySQL Server 
$DB_Username = "******";                 //your MySQL User Name 
$DB_Password = "*****";             //your MySQL Password 
$DB_DBName = "*******";             //your MySQL Database Name 
$DB_TBLName = "********";               //your MySQL Table Name  

 $filename = "excelfilename";         //File Name

 //create MySQL connection
 $sql = "Select * from $DB_TBLName";
 $Connect = @mysql_connect($DB_Server, $DB_Username, $DB_Password)
 or die("Couldn't connect to MySQL:<br>" . mysql_error() . "<br>" . mysql_errno());
 //select database
 $Db = @mysql_select_db($DB_DBName, $Connect)
 or die("Couldn't select database:<br>" . mysql_error(). "<br>" . mysql_errno());
 //execute query
 $result = @mysql_query($sql,$Connect)
 or die("Couldn't execute query:<br>" . mysql_error(). "<br>" . mysql_errno());
 $file_ending = "xls";

//header info for browser
 header("Content-Type: application/xls");
 header("Content-Disposition: attachment; filename=$filename.xls");
 header("Pragma: no-cache");
 header("Expires: 0");

/*******Start of Formatting for Excel*******/
 //define separator (defines columns in excel & tabs in word)
 $sep = "\t"; //tabbed character

//start of printing column names as names of MySQL fields
 for ($i = 0; $i < mysql_num_fields($result); $i++) {
 echo mysql_field_name($result,$i) . "\t";
 }
 print("\n");
 //end of printing column names

//start while loop to get data
 while($row = mysql_fetch_row($result))
 {
 $schema_insert = "";
 for($j=0; $j<mysql_num_fields($result);$j++)
 {
 if(!isset($row[$j]))
 $schema_insert .= "NULL".$sep;
 elseif ($row[$j] != "")
 $schema_insert .= "$row[$j]".$sep;
 else
 $schema_insert .= "".$sep;
 }
 $schema_insert = str_replace($sep."$", "", $schema_insert);
 $schema_insert = preg_replace("/\r\n|\n\r|\n|\r/", " ", $schema_insert);
 $schema_insert .= "\t";
 print(trim($schema_insert));
 print "\n";
 }
 ?>

Answer 1

You have to write what is charset of you database. If it is UTF8 try to execute query "SET NAMES utf8" after connection is established ;

And be shure that encoding of you page is UTF8. You can check encoding in Notepad++ utility

Answer 2

Problem is your output is in ISO-8859-2 but excel expects Windows-1250 which has few characters shuffled around for Windows-1252 compatibility.

You can either convert your output to Windows-1250

echo mb_convert_encoding($str, 'Windows-1250', 'ISO-8859-2');

Or convert to utf8:

add utf8 BOM after headers and first thing as file content:

echo "\xEF\xBB\xBF";

and convert data to utf8

echo mb_convert_encoding($str, 'UTF-8', 'ISO-8859-2');

If you have older excel that does not support utf8 you are out of luck.

By default excel assumes windows default locale which is different for people from different locations ie person in US will likely see your text as "Brze¶æ, Bia³oru¶" instead
