使用php发布数据[重复]

I want to know how to post data with php, for example get the input from the local php then write to the input with id on another webpage. I think that those are called PHP bots, but I didn't quite understand the function. If you could just show me the code, if this is possible.

UPDATE: To make it cleaner - how to "write" to an input on another page with PHP.

To Post Data to an URL, you can use CURL for that.

$my_url = 'http://www.google.com';
$post_vars = 'postvar1=' . $postvar1 . '&postvar2=' . $postvar2;

$curl = curl_init($my_url);
curl_setopt($curl, CURLOPT_POST, 1);
curl_setopt($curl, CURLOPT_POSTFIELDS, $post_vars);
curl_setopt($curl, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($curl, CURLOPT_HEADER, 0);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);

$response = curl_exec($curl);

UPDATE

If you don´t want to use CURL you can try it this way:

$server= 'www.someserver.com';
$url = '/path/to/file.php';
$content = 'name1=value1&name2=value2';
$content_length = strlen($content);
$headers= "POST $url HTTP/1.0
Content-type: text/html
Host: $server
Content-length: $content_length

";
$fp = fsockopen($server, $port, $errno, $errstr);
if (!$fp) return false;
fputs($fp, $headers);
fputs($fp, $content);
$ret = "";
while (!feof($fp)) {
$ret.= fgets($fp, 1024);
}
fclose($fp);
print $ret;

and if you´re using PHP5 here's a function you can use to post data to an URL:

function do_post_request($url, $data, $optional_headers = null)
{
  $params = array('http' => array(
              'method' => 'POST',
              'content' => $data
            ));
  if ($optional_headers !== null) {
    $params['http']['header'] = $optional_headers;
  }
  $ctx = stream_context_create($params);
  $fp = @fopen($url, 'rb', false, $ctx);
  if (!$fp) {
    throw new Exception("Problem with $url, $php_errormsg");
  }
  $response = @stream_get_contents($fp);
  if ($response === false) {
    throw new Exception("Problem reading data from $url, $php_errormsg");
  }
  return $response;
}

this function is from here

and to use this function do something like

<?php

do_post_request('http://search.yahoo.com/', 'p=hello+yahoo')

?>

this will search for "hello yahoo"
