方法1: 用file_get_contents 以get方式获取内容:

方法2: 用fopen打开url, 以get方式获取内容:


方法3:用file_get_contents函数,以post方式获取url

 ‘bar');
$data = http_build_query($data);

$opts = array (
‘http' => array (
‘method' => ‘POST',
‘header'=> “Content-type: application/x-www-form-urlencodedrn” .
“Content-Length: ” . strlen($data) . “rn”,
‘content' => $data
)
);

$context = stream_context_create($opts);
$html = file_get_contents(‘http://localhost/e/admin/test.html', false, $context);

echo $html;
?>

方法4:用fsockopen函数打开url,以get方式获取完整的数据,包括header和body,fsockopen需要 PHP.ini 中 allow_url_fopen 选项开启


方法5:用fsockopen函数打开url,以POST方式获取完整的数据,包括header和body

$value)
$values[]=”$key=”.urlencode($value);
$data_string=implode(“&”,$values);

// Find out which port is needed – if not given use standard (=80)
if(!isset($URL_Info["port"]))
$URL_Info["port"]=80;

// building POST-request:
$request.=”POST “.$URL_Info["path"].” HTTP/1.1n”;
$request.=”Host: “.$URL_Info["host"].”n”;
$request.=”Referer: $referern”;
$request.=”Content-type: application/x-www-form-urlencodedn”;
$request.=”Content-length: “.strlen($data_string).”n”;
$request.=”Connection: closen”;

$request.=”Cookie:  $cookien”;

$request.=”n”;
$request.=$data_string.”n”;

$fp = fsockopen($URL_Info["host"],$URL_Info["port"]);
fputs($fp, $request);
while(!feof($fp)) {
$result .= fgets($fp, 1024);
}
fclose($fp);

return $result;
}

?>

方法6:使用curl库,使用curl库之前,可能需要查看一下php.ini是否已经打开了curl扩展
