一、推荐方法 CURL获取
$c =curl_init();
$url = 'www.jb51.net';
curl_setopt($c, CURLOPT_URL, $url);
curl_setopt($c, CURLOPT_RETURNTRANSFER, 1);
$ data =curl_exec($c);
curl_close($c);
$pos = strpos($data,'utf-8');
if($pos===false){$data = iconv("gbk" ,"utf-8",$data);}
preg_match("/
二、使用file()関数数
$lines_array = file('http://www.jb51.net/');
$lines_string = implode('', $lines_array);
$pos = strpos($lines_string,'utf-8');
if($pos===false){$lines_string = iconv("gbk","utf-8",$lines_string);}
eregi( "
三、file_get_contentsを使用します
$content=file_get_contents("http://www.jb51.net/");
$pos = strpos($content,'utf-8');
if($pos===false ){$content = iconv("gbk","utf-8",$content);}
$postb=strpos($content,'
