處理HTTP郵政與陣列（沒有捲曲）

Question

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; 
} 

不POST數組：

$postdata = array( 
    'send_email' => $_REQUEST['send_email'], 
    'send_text' => $_REQUEST['send_text']); 

我怎樣才能得到獨立的數組元素個別PHP變種？ POST數據處理器的頁面

部分：

... 
$message = $_REQUEST['postdata']['send_text']; 
... 

什麼錯？

試試這個：

在客戶端：

function do_post_request ($url, $data, $headers = array()) { 
    // Turn $data into a string 
    $dataStr = http_build_query($data); 
    // Turn headers into a string 
    $headerStr = ''; 
    foreach ($headers as $key => $value) if (!in_array(strtolower($key),array('content-type','content-length'))) $headerStr .= "$key: $value\r\n"; 
    // Set standard headers 
    $headerStr .= 'Content-Length: '.strlen($data)."\r\nContent-Type: application/x-www-form-urlencoded" 
    // Create a context 
    $context = stream_context_create(array('http' => array('method' => 'POST', 'content' => $data, 'header' => $headerStr))); 
    // Do the request and return the result 
    return ($result = file_get_contents($url, FALSE, $context)) ? $result : FALSE; 
} 

$url = 'http://sub.domain.tld/file.ext'; 
$postData = array( 
    'send_email' => $_REQUEST['send_email'], 
    'send_text' => $_REQUEST['send_text'] 
); 
$extraHeaders = array(
    'User-Agent' => 'My HTTP Client/1.1' 
); 

var_dump(do_post_request($url, $postData, $extraHeaders)); 

在服務器端：

print_r($_POST); 
/* 
    Outputs something like: 
    Array (
     [send_email] => Some Value 
     [send_text] => Some Other Value 
    ) 
*/ 

$message = $_POST['send_text']; 
echo $message; 
// Outputs something like: Some Other Value
