復(fù)制代碼 代碼如下:

//米爾軍事網(wǎng)采用 gzip壓縮網(wǎng)頁
//file_get_contents 直接獲得的網(wǎng)頁是亂碼。
header('Content-Type:text/html;charset=utf-8' );
$url = 'http://www.miercn.com';
$file = fopen($url, "rb");
//只讀2字節(jié) 如果為(16進制)1f 8b (10進制)31 139則開啟了gzip ;
$bin = fread($file, 2);
fclose($file);
$strInfo = @unpack("C2chars", $bin);
$typeCode = intval($strInfo['chars1'].$strInfo['chars2']);
$isGzip = 0;
switch ($typeCode)
{
case 31139:
//網(wǎng)站開啟了gzip
$isGzip = 1;
break;
default:
$isGzip = 0;
}
$url = $isGzip ? "compress.zlib://".$url:$url; // 三元表達式
$mierHtml = file_get_contents($url); //獲得米爾軍事網(wǎng)數(shù)據(jù)
$mierHtml = iconv("gbk","utf-8",$mierHtml);
echo $mierHtml;
