Sample code for using socket in PHP to simulate post or get data submission in HTTP_PHP Tutorial

废话不多说。直接上代码：
sock_post.php:

复制代码 代码如下:

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:

复制代码 代码如下:

echo "post:";
print_r($_POST);
echo 'get:';
print_r($_GET);
?>
