     )

// Fetch the URL's contents
$contents = file_get_contents('http://www.111cn.net', 0, $context);

$opts = array(
'http'=>array(
'method'=>"GET",
'timeout'=>60,
)
);
$context = stream_context_create($opts);
$html =file_get_contents('http://www.111cn.net', false, $context);

$cnt=0; 

while($cnt

function Post($url, $post = null)
{
$context = array();

if (is_array($post))
{
ksort($post);

$context['http'] = array
(

'timeout'=>60,
'method' => 'POST',
'content' => http_build_query($post, '', '&'),

}

return file_get_contents($url, false, stream_context_create($context));
}
