php post请求
在php里面怎么提交一个post请求,我要请求一个网址,传参数进去。他会返回一个xml格式的文件结果。在php里面怎么post。

------解决方案--------------------
function _xpost($url,$p)
{
$f='';
$data='';
foreach($p as $k=>$v)
{
$data.=$f.$k.'='.urlencode($v);
$f='&';
}

$curl = curl_init($url);
curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, 1); 
curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false); 
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($curl, CURLOPT_POST, 1);
curl_setopt($curl, CURLOPT_POSTFIELDS, $data);
$res = curl_exec($curl);

if(curl_errno($curl))
{
echo 'Curl error: ' . curl_error($curl);
}
curl_close($curl);
return $res;
}

$x=_xpost('http://abc.com/aa.php',array( 'username'=>$uname,

preg_match('/(.*?)/s',$xml,$m);
echo $m[1];
