Send $_post Variables Without Forms

Using the function is easy and can be carried out with just two parameters:

1. The URL of the page to pass the parameters through too
2. An array of variable => value pairs to pass as $_POST parameters

 

$context = array(
    'post_variable1' => 'post_value1',
    'post_variable2' => 'post_value2',
    'post_variable3' => 'post_value3'
);

$something = sendPost("some-url.php", $context);

and here is the sendPost function:
 

function sendPost($url, $context) {
    $context = array_change_key_case($context, CASE_LOWER);
    $contextSize = sizeof($context);
    $contextKeys = array_keys($context);
    $data = "";
    foreach ($contextKeys as $key) {
        $amp = $contextKeys === FALSE ? "" : "&";
        $data .= urlencode($key)."=".urlencode($context[$key]).$amp;
    }
 
    list($host,$url) = explode('/',$url,2);
    $sock = fsockopen($host, 80, $errno, $errstr, 1);
    if (!$sock) { die("$errstr ($errno) in ".__FILE__." (".__LINE__.")\n"); }
    $http_request = "POST /".$url." HTTP/1.1\r\n";
    $http_request .= "Host: ".$host."\r\n";
    $http_request .= "Content-type: application/x-www-form-urlencoded\r\n";
    $http_request .= "Content-length: " . strlen($data) . "\r\n";
    $http_request .= "Accept: */*\r\n";
    $http_request .= "\r\n";
    $http_request .= "$data\r\n";
    $http_request .= "\r\n";
    fwrite($sock,$http_request);
    $response_headers = array();
    while ($str = trim(fgets($sock))) {
        array_push($response_headers,$str);
    }
    fclose($sock);
    $errors = true;
    foreach($response_headers as $response_header) {
        if($response_header == 'HTTP/1.1 200 OK') {
            $errors = false;
        }
    }
    if (!$errors)
        return true;
    else
        return false;
}
