php uses fsockopen GET/POST to submit forms and upload files

1.GET

get.php

 'fdipzone',
    'gender' => 'man'
);
$url = $url.'?'.http_build_query($param);
// create connect
$fp = fsockopen($host, $port, $errno, $errstr, $timeout);
if(!$fp){
    return false;
}
// send request
$out = "GET ${url} HTTP/1.1\r\n";
$out .= "Host: ${host}\r\n";
$out .= "Connection:close\r\n\r\n";
fputs($fp, $out);
// get response
$response = '';
while($row=fread($fp, 4096)){
    $response .= $row;
}
fclose($fp);
$pos = strpos($response, "\r\n\r\n");
$response = substr($response, $pos+4);
echo $response;
?>

getapi.php

25eed5875dc39cb4ccbae3d67327971a';
echo 'gender='.$gender;
?>

2.POST

post.php

 'fdipzone',
    'gender' => 'man',
    'photo' => file_get_contents('photo.jpg')
);
$data = http_build_query($param);
// create connect
$fp = fsockopen($host, $port, $errno, $errstr, $timeout);
if(!$fp){
    return false;
}
// send request
$out = "POST ${url} HTTP/1.1\r\n";
$out .= "Host:${host}\r\n";
$out .= "Content-type:application/x-www-form-urlencoded\r\n";
$out .= "Content-length:".strlen($data)."\r\n";
$out .= "Connection:close\r\n\r\n";
$out .= "${data}";
fputs($fp, $out);
// get response
$response = '';
while($row=fread($fp, 4096)){
    $response .= $row;
}
fclose($fp);
$pos = strpos($response, "\r\n\r\n");
$response = substr($response, $pos+4);
echo $response;
?>

postapi.php

';
echo 'gender='.$gender.'
';
echo '';
?>

3. Upload file

file .php

 'fdipzone',
    'gender' => 'man',
);
$file_data = array(
    array(
        'name' => 'photo',
        'filename' => 'photo.jpg',
        'path' =>'photo.jpg'
    )
);
// create connect
$fp = fsockopen($host, $port, $errno, $errstr, $timeout);
if(!$fp){
    return false;
}
// send request
srand((double)microtime()*1000000);
$boundary = "---------------------------".substr(md5(rand(0,32000)),0,10);
$data = "--$boundary\r\n";
// form data
foreach($form_data as $key=>$val){
    $data .= "Content-Disposition: form-data; name=\"".$key."\"\r\n";
    $data .= "Content-type:text/plain\r\n\r\n";
    $data .= rawurlencode($val)."\r\n";
    $data .= "--$boundary\r\n";
}
// file data
foreach($file_data as $file){
    $data .= "Content-Disposition: form-data; name=\"".$file['name']."\"; filename=\"".$file['filename']."\"\r\n";
    $data .= "Content-Type: ".mime_content_type($file['path'])."\r\n\r\n";
    $data .= implode("",file($file['path']))."\r\n";
    $data .= "--$boundary\r\n";
}
$data .="--\r\n\r\n";
$out = "POST ${url} HTTP/1.1\r\n";
$out .= "Host:${host}\r\n";
$out .= "Content-type:multipart/form-data; boundary=$boundary\r\n"; // multipart/form-data
$out .= "Content-length:".strlen($data)."\r\n";
$out .= "Connection:close\r\n\r\n";
$out .= "${data}";
fputs($fp, $out);
// get response
$response = '';
while($row=fread($fp, 4096)){
    $response .= $row;
}
fclose($fp);
$pos = strpos($response, "\r\n\r\n");
$response = substr($response, $pos+4);
echo $response;
?>

fileapi.php

';
echo 'gender='.$gender.'
';
if(move_uploaded_file($_FILES['photo']['tmp_name'], UPLOAD_PATH.'/'.$filename)){
    echo '';
}
