废话不多说。直接上代码：
sock_post.PHP:
function sock_post($url,$data='') {
$url = parse_url($url);
$url['scheme'] || $url['scheme'] = 'http';
$url['host'] || $url['host'] = $_SERVER['HTTP_HOST'];
$url['path'][0] != '/' && $url['path'] = '/'.$url['path'];
$query = $data;
if(is_array($data)) $query = http_build_query($data);
$fp = @fsockopen($url['host'],$url['port'] ? $url['port'] : 80);
if (!$fp) return "Failed to open socket to $url[host]";
fputs($fp,sprintf("POST %s%s%s HTTP/1.0/n",$url['path'],$url['query'] ? "?" : "",$url['query']));
fputs($fp,"Host: $url[host]/n");
fputs($fp,"Content-type: application/x-www-form-urlencoded/n");
fputs($fp,"Content-length: " . strlen($query) . "/n");
fputs($fp,"Connection: close/n/n");
fputs($fp,"$query/n");
$line = fgets($fp,1024);
if (@!eregi("^HTTP/1/.. 200",$line)) return;
$results = "";
$inheader = 1;
while(!feof($fp)) {
$line = fgets($fp,1024);
if ($inheader && ($line == "/n" || $line == "/r/n")) {
$inheader = 0;
}elseif (!$inheader) {
$results .= $line;
}
}
fclose($fp);
return $results;
}
$re = sock_post('http://localhost/direct_post/get_post.PHP?id=1',array('wel'=>'hello'));
echo $re;
?>
get_post.PHP:
echo "post:";
print_r($_POST);
echo 'get:';
print_r($_GET);
?>
