和
$d = fopen("chat.txt", "a");
$c=$_GET['c'];
if($c=='') die();
fwrite($d,$c.'||');
fclose($d);
but in =ie only= utf-8 character show "?" or "[]" . my encoding Utf-8 Without BOM and i use this
但在 =ie only= utf-8 字符中显示“？” 或者 ”[]” 。我的编码 Utf-8 没有 BOM，我使用这个
header('Content-type: text/html; charset=UTF-8');
and This :
和这个 ：
<meta http-equiv="content-type" content="text/html; charset=utf-8" />
my defult encoding in php.ini is utf-8 but yet show ? . i see chat.txt file and character right in file but when with ie save in file And when show in page show "?" instead of right .
我在 php.ini 中的默认编码是 utf-8 但还显示？. 我在文件中看到 chat.txt 文件和字符，但是当 ie 保存在文件中时，当在页面中显示时显示“？” 而不是对。

Use this function instead of fopen while reading but not while writing
在读取时使用此函数而不是 fopen 而不是在写入时
function utf8_fopen_read($fileName) {
$fc = iconv('windows-1250', 'utf-8', file_get_contents($fileName));
$handle=fopen("php://memory", "rw");
fwrite($handle, $fc);
fseek($handle, 0);
return $handle;
}

In your case
在你的情况下
$d = utf8_fopen_read("chat.txt", "r");
$content=fread($d,filesize('chat.txt'));
$bn=explode('||',$content);
foreach($bn as $bn)
echo $bn.'<br>';
Try this
尝试这个
$content = iconv('windows-1250', 'utf-8', file_get_contents($fileName));
$bn = mb_split('||',$content);
foreach($bn as $b)
echo $b.'<br>';

The TXT was saved with utf8 encode? You need to ensure that the TXT codification is utf-8, otherwise you will need use utf8_encode function
TXT 是用 utf8 编码保存的吗？需要确保TXT编码为utf-8，否则需要使用utf8_encode函数

You can encode the string you are outputting, $bn in this case, using utf8_encode() like this:
您可以像这样使用 utf8_encode() 对要输出的字符串进行编码，在这种情况下为 $bn：
$d = fopen("chat.txt", "r");
$content=fread($d,filesize('chat.txt'));
$bn=explode('||',$content);
foreach($bn as $bn)
echo utf8_encode($bn).'<br>';
Try that and see if it's still wierd.
尝试一下，看看它是否仍然很奇怪。
