UTF8 中的制表符字符

Question

我正在尝试创建我的 mysql table 的 xls 文件输出，我需要文件 export.php 的 UTF8 编码，因为斯洛伐克字符 - ľ č š ť ž ý .. .但是当我将它转换为 UTF8 时我的脚本无法打印 \t character

// part of export.php

header("Content-Type: application/xls");
header("Content-Disposition: attachment; filename=export.xls");
header("Pragma: no-cache");
header("Expires: 0");
$sql = ("select * from zakaznici");
$db->query("SET NAMES 'utf8'");

if (!$result = $db->query($sql))
{
    die('There was an error running the query [' . $db->error . ']');
}

// define separator (defines columns in excel & tabs in word)

$sep = "\t"; //tabbed character

// start of printing column names as names of MySQL fields

$finfo = $result->fetch_fields();

foreach($finfo as $val)
{
    printf("%s\t", $val->name);
}

print ("\n");
$schema_insert = "";

while ($ser = $result->fetch_assoc())
{
    $id = $ser['id'];
    $email = $ser['email'];
    $password = $ser['pass'];
    $schema_insert.= $id . $sep . $email . $sep . $password;
    print ("\n");
}

$schema_insert = str_replace($sep . "$", "", $schema_insert);
$schema_insert = preg_replace("/\r\n|\n\r|\n|\r/", " ", $schema_insert);
$schema_insert.= "\t";
print (trim($schema_insert));
print "\n";

\n 字符工作正常..只有 \t 与 UTF8 不工作谢谢你的帮助

我的猜测是，生成的文件开头缺少 UTF-8 BOM 标记文件。因此，我建议在内容输出之前添加 BOM，如下所示：

print "\xEF\xBB\xBF";
print trim($schema_insert);
print "\n";

有人建议使用mb_convert_encoding()，看这里：php header excel and utf-8
