使用HTTP Get请求的PHP URL编码

Question

I've set up a PHP script to send a text message using the Nexmo API, however there's a problem with how I'm encoding the HTTP Get request. The script pulls some variables from stored data, and then fires. I'm not experienced with PHP and have spent so much time on this already, this is my last resort, is anyone able to see where I've gone wrong in the following code?

The intended format for the request:

https://rest.nexmo.com/sms/json?api_key=XXX&api_secret=XXX&to=XXX&from=XXX&text=XXX

The code:

function sendText () {

    $api_key = $settings['consumer_key'];
    $api_secret = $settings['consumer_secret'];
    $recipient = $settings['recipient'];
    $from = $settings['from'];
    $text = $settings['sms_contents'];

    $url = 'https://rest.nexmo.com/sms/json';
    $data = array_merge($data, array('api_key' => $api_key, 'api_secret' => $api_secret, 'to' => $recipient, 'from' => $from, 'text' => $text));

    $post = '';
    foreach($data as $k => $v){
        $post .= "&$k=$v";
    }

    $opts = array('http' =>
            array(
                'method'  => 'POST',
                'header'  => 'Content-type: application/x-www-form-urlencoded',
                'content' => $post
            )
        );
    $context = stream_context_create($opts);
    $from_nexmo = file_get_contents($url, false, $context);

    }

sendText();

Try to use urlencode() for transfered values:

$post = array();

foreach($data as $k => $v){
    $post[] = $k . '=' . urlencode($v);
}

$post = implode('&', $post);

$opts = array('http' =>
        array(
            'method'  => 'POST',
            'header'  => 'Content-type: application/x-www-form-urlencoded',
            'content' => $post
        )
    );
