我有这个代码用于以CSV格式导出查询,问题是,如果我用Excel打开它,俄语字符将不会显示,但如果我用数字(Mac)打开它们就会显示。 / p>

现在,我无法解决这个问题。我添加了一些我在互联网上看到的线条而没有...

<?php
/*

 /*

$conn = mysql_connect('', '', '') or die(mysql_error());

mysql_query("SET NAMES UTF8");

$query = sprintf('SELECT fields FROM table');
$result = mysql_query($query, $conn) or die(mysql_error($conn));

/*

}

function echocsv($fields)
{
    $separator = '';
    foreach ($fields as $field) {
        if (preg_match('/\\r|\\n|,|"/', $field)) {

        }
        echo $separator . $field;
        $separator = ',';
    }
    echo "\r\n";
}

未为UTF-8编码数据创建脚本。它几乎按原样转储数据。生成的CSV文件将包含(可能)有效的UTF-8编码数据,但不包含签名。在没有签名的情况下,某些软件会使用启发式方法来检测编码;其他人,比如Excel,不会。

您必须告诉excel将文件视为UTF-8编码。为此,您需要在Excel中导入文件(数据&gt;获取外部数据&gt;从文本中)而不是直接打开它(双击或使用文件&gt;打开)。在文本导入向导中,选择适当的编码,Excel应正确导入数据。请参阅下面的屏幕截图。

或者,您可以尝试添加UTF-8 signature manually。我自己没试过。

// ...
header('Content-Disposition: attachment;filename=hostess.csv');
echo "\xEF\xBB\xBF";
// ...

This is what you see if you open the file directly This is what you see if you choose correct encoding
