POST and GET without cURL PHP - php

Question

I tried some times release POST and GET in this site http://www.sefaz.pe.gov.br/sintegra, but it doesn´t work
// POST
$data = array('CNPJ' => '02340534000192', 'consulta' => 'OK', 'vazio' => '');
$html = $this->HTTP_Post('http://www.sefaz.pe.gov.br/sintegra/consulta/consulta.asp', $data, $cookie);
$arr = split("Set-Cookie:", $html);
$cookie="";
$count=1;
while ($count < count($arr))
{
$cookie.=substr($arr[$count].";", 0, strpos($arr[$count].";",";")+1);
$count++;
}
// GET after POST
echo $this->get_url('http://www.sefaz.pe.gov.br/sintegra/consulta/exibirResultado.asp', $cookie);
I tried file_get_contents and curl too... both without success
function get_url($url,$cookie=false)
{
$url = parse_url($url);
$query = $url[path]."?".$url[query];
echo "Query:".$query;
$fp = fsockopen( $url[host], $url[port]?$url[port]:80 , $errno, $errstr, 30);
if (!$fp)
{
return false;
}
else
{
$request = "GET $query HTTP/1.1\r\n";
$request .= "Host: $url[host]\r\n";
$request .= "Connection: Keep-Alive\r\n";
if($cookie) $request.="Cookie: $cookie\n";
$request.="\r\n";
fwrite($fp,$request);
while (!feof($fp))
{
$result .= fgets($fp, 128);
}
fclose($fp);
return $result;
}
}
function HTTP_Post($URL,$data,$cookie, $referrer="")
{
$URL_Info=parse_url($URL);
if($referrer=="") $referrer="111";
foreach($data as $key=>$value)
$values[]="$key=".urlencode($value);
$data_string=implode("&",$values);
if(!isset($URL_Info["port"]))
$URL_Info["port"]=80;
$request.="POST ".$URL_Info["path"]." HTTP/1.1\n";
$request.="Host: ".$URL_Info["host"]."\n";
$request.="Referer: $referer\n";
$request.="Content-type: application/x-www-form-urlencoded\n";
$request.="Content-length: ".strlen($data_string)."\n";
$request.="Connection: Keep-Alive\n";
$request.="Cookie: $cookie\n";
$request.="\n";
$request.=$data_string."\n";
$fp = fsockopen($URL_Info["host"],$URL_Info["port"]);
fputs($fp, $request);
while(!feof($fp))
{
$result .= fgets($fp, 1024);
}
fclose($fp);
return $result;
}
functions GET and POST with fsocket.
any ideas are welcome
Thanks

Answer 1

I think you can do file_get_contents for GET
or http://php.net/manual/en/context.http.php for POST
Example from php.net website
$postdata = http_build_query(
array(
'var1' => 'some content',
'var2' => 'doh'
)
);
$opts = array('http' =>
array(
'method' => 'POST',
'header' => 'Content-type: application/x-www-form-urlencoded',
'content' => $postdata
)
);
$context = stream_context_create($opts);
$result = file_get_contents('http://example.com/submit.php', false, $context);
