哪位大哥用过fsockopen函数

哪位大哥用过fsockopen函数，它执行的效果和php的配置是不是有关？
我在万网提供的空间中使用该函数和其他网站取得了联系而在新网提供的空间中却不行，很是奇怪.

我使用了一个类：
require("include/http.class.php");

$thisHttp = new cHTTP();
$thisHttp->getPage("http://www.ytht.net");
$content = $thisHttp->getContent();
if ( $content != "" )
echo $content;
else
echo "test";
该类相关代码为：
class cHTTP {

var $referer;
var $postStr;

var $retStr;
var $theData;

var $theCookies;
var $proxy_host="";
var $proxy_port="0";


function clsHTTP(){

}


function setReferer($sRef){
$this->referer = $sRef;
}


function addField($sName, $sValue){
$this->postStr .= $sName . "=" . $this->HTMLEncode($sValue) . "&";
}
function clearFields(){
$this->postStr = "";
}

function checkCookies(){
$cookies = explode("Set-Cookie:", $this->theData );
$i = 0;
if ( count($cookies)-1 > 0 ) {
while(list($foo, $theCookie) = each($cookies)) {
if (! ($i == 0) ) {
@list($theCookie, $foo) = explode(";", $theCookie);
list($cookieName, $cookieValue) = explode("=", $theCookie);
@list($cookieValue, $foo) = explode("\r\n", $cookieValue);
$this->setCookies(trim($cookieName), trim($cookieValue));
}
$i++;
}
}
}

function setCookies($sName, $sValue){

$total = count(explode($sName, $this->theCookies));

if ( $total > 1 ) {
list($foo, $cValue) = explode($sName, $this->theCookies);
list($cValue, $foo) = explode(";", $cValue);

$this->theCookies = str_replace($sName . $cValue . ";", "", $this->theCookies);
}
$this->theCookies .= $sName . "=" . $this->HTMLEncode($sValue) . ";";
}

function getCookies($sName){
@list($foo, $cValue) = explode($sName, $this->theCookies);
@list($cValue, $foo) = explode(";", $cValue);
return substr($cValue, 1);
}

// Cookie format: Name1 = Value1;<NameN = ValueN;>
function getFirstCookieName(){
@list($cValue, $foo) = explode("=", $this->theCookies);
return $cValue;
}

function getFirstCookieValue(){
@list($foo, $cValue) = explode("=", $this->theCookies);
@list($cValue, $foo) = explode(";", $cValue);
return $cValue;
}
//

function clearCookies(){
$this->theCookies = "";
}


function getContent(){
@list($header, $foo) = explode("\r\n\r\n", $this->theData);
@list($foo, $content) = explode($header, $this->theData);
return substr($content, 4);
}

function getHeaders(){
list($header, $foo) = explode("\r\n\r\n", $this->theData);
list($foo, $content) = explode($header, $this->theData);
return $header;
}

function getHeader($sName){
list($foo, $part1) = explode($sName . ":", $this->theData);
list($sVal, $foo) = explode("\r\n", $part1);
return trim($sVal);
}

function postPage($sURL){
$host = "";
$port = "";
if ( $this->proxy_host != "" )
{
$request = $sURL;

先谢谢诸位了！

如果是报fsockopen函数未定义，那么就是被禁用了

应该不会，要不把你的代码贴出来让大家看看
