Формирование POST запроса, php

cUrl в помощь.

Как именно, можешь показать?

Можно сделать так.

	//Функция отправляет POST запрос и возвращает результат его выполнения

	function pc_post_request($host,$url,$content='')

	{

	    $timeout = 10;

	    $a = array();

	    if (is_array($content)) {

	        foreach ($content as $k => $v) {

	            array_push($a,($k).'='.($v));

	        }

	    }

	    $content_string = join('&',$a);

	    $content_length = strlen($content_string);

	    $request_body = "POST $url HTTP/1.0

Host: $host

Content-type: application/x-www-form-urlencoded

Content-length: $content_length



$content_string";



	    $sh = fsockopen($host,80,&$errno,&$errstr,$timeout)

	        or die("can't open socket to $host: $errno $errstr");



	    fputs($sh,$request_body);

	    $response = '';

	    while (! feof($sh)) {

	        $response .= fread($sh,16384);

	    }

	    fclose($sh) or die("Can't close socket handle: $php_errormsg");



	    list($response_headers,$response_body) = explode("\r\n\r\n",$response,2);

	    $response_header_lines = explode("\r\n",$response_headers);



	    // first line of headers is the HTTP response code

	    $http_response_line = array_shift($response_header_lines);

	    if (preg_match('@^HTTP/[0-9]\.[0-9] ([0-9]{3})@',$http_response_line,

	                   $matches)) {

	        $response_code = $matches[1];

	    }



	    // put the rest of the headers in an array

	    $response_header_array = array();

	    foreach ($response_header_lines as $header_line) {

	        list($header,$value) = explode(': ',$header_line,2);

	        $response_header_array[$header] = $value;

	    }

	    $response_body = iconv("utf-8","windows-1251",$response_body);



	    return array($response_code,$response_header_array,$response_body);

	}

$ch = curl_init();

//curl_setopt($ch, CURLOPT_PROXY, "1.2.3.4:123"); //если нужен прокси

curl_setopt($ch, CURLOPT_POST, 1);

curl_setopt($ch, CURLOPT_URL, "http://www.site.com/form.php"); //куда шлем

curl_setopt($ch, CURLOPT_POSTFIELDS, "x=231&y=342"); //что шлем

curl_setopt($ch, CURLOPT_REFERER, "http://www.site.com");

curl_setopt($ch, CURLOPT_USERAGENT, "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.0; MyIE2; .NET CLR 1.1.4322)");

curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);

curl_setopt($ch, CURLOPT_HEADER, 1);

curl_setopt($ch, CURLOPT_NOBODY, 0);

$result=curl_exec ($ch);

curl_close ($ch);

echo $result;
