我必须获取波斯语页面的内容并向某些用户显示该页面的一部分。问题是在过滤页面内容后，我无法使用正确的编码显示内容。该网页位于 sena.ir，这是我要显示的原始网页部分的屏幕截图：
替代文本http://img502.imageshack.us/img502/983/original.gif
这是我得到的：

这是我用来获取页面内容的函数：
function getPage($url, $referer="", $timeout="", $header=""){
if(!isset($timeout))
$timeout=30;
$curl = curl_init();
if(strstr($referer,"://")){
curl_setopt ($curl, CURLOPT_REFERER, $referer);
}
$headers [] = 'Accept: image/gif, image/x-bitmap, image/jpeg, image/pjpeg';
$headers [] = 'Connection: Keep-Alive';
$headers [] = 'Content-type: application/x-www-form-urlencoded;charset=utf-8 '; // I Tried iso-..... as well but no chance
$user_agent = 'Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 5.1; .NET CLR 1.0.3705; .NET CLR 1.1.4322; Media Center PC 4.0)';
$compression = "gzip";
curl_setopt ($curl, CURLOPT_HTTPHEADER, $headers );
curl_setopt ($curl, CURLOPT_HEADER, 0 );
curl_setopt ($curl, CURLOPT_USERAGENT, $user_agent );
curl_setopt ($curl, CURLOPT_RETURNTRANSFER, 1 );
curl_setopt ($curl, CURLOPT_FOLLOWLOCATION, 1 );
curl_setopt ($curl, CURLOPT_POST, 0 );
curl_setopt ($curl, CURLOPT_ENCODING, $compression );
curl_setopt ($curl, CURLOPT_TIMEOUT, 300 );
curl_setopt ($curl, CURLOPT_SSL_VERIFYHOST, 0 );
curl_setopt ($curl, CURLOPT_SSL_VERIFYPEER, 0 );
curl_setopt ($curl, CURLOPT_URL, $url);
$html = curl_exec ($curl);
curl_close ($curl);
return $html;
}
$content = getPage("http://sena.ir/");
$p1 = strpos($content,'<TABLE cellSpacing="3" cellPadding="3" width="100%" border="0">');
$p2 = strpos($content,"</TABLE>",$p1);
$content = substr($content, $p1, $p2-$p1);
echo $content;
数据不是问题。 输出是问题所在。 由于类似代理的函数会删除 html 的标头和编码声明，因此您必须在输出过滤后的数据之前添加这些行：
<html lang="fa">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
