White spaces in postFields in PHP Curl

问题

I have the next code:

$c = curl_init();
curl_setopt($c, CURLOPT_URL, 'http://www.mydomain.com/test.php');
curl_setopt($c, CURLOPT_POST, true);
curl_setopt($c, CURLOPT_POSTFIELDS,"First Name=Jhon&Last Name=bt");
curl_exec ($c);
curl_close ($c);

My problem is with the spaces in this code:

"First Name=Jhon&Last Name=bt"

I tried the next code:

$test=rawurlencode("First Name=Jhon&Last Name=bt");

$c = curl_init();
curl_setopt($c, CURLOPT_URL, 'http://www.mydomain.com/test.php');
curl_setopt($c, CURLOPT_POST, true);
curl_setopt($c, CURLOPT_POSTFIELDS,$test);
curl_exec ($c);
curl_close ($c);

Also I tried

$first_name=rawurlencode("First Name");

$last_name=rawurlencode("Last Name");

$c = curl_init();
curl_setopt($c, CURLOPT_URL, 'http://www.mydomain.com/test.php');
curl_setopt($c, CURLOPT_POST, true);
curl_setopt($c, CURLOPT_POSTFIELDS,"$first_name=Jhon&$last_name=bt");
curl_exec ($c);
curl_close ($c);

What is my error? is not working. I need to send with the name of variables "First Name" and "Last Name". Thanks for your help.

standalone curl ENcoding.

PHP urlencoding

Just encode the values first, then pass to curl as post field options.

$encodedValue = urlEncode("this has spaces - oh no!");
$c = curl_init();
curl_setopt($c, CURLOPT_URL, 'http://www.mydomain.com/test.php');
curl_setopt($c, CURLOPT_POST, true);
curl_setopt($c, CURLOPT_POSTFIELDS , "value=" . $encodedValue);
curl_exec ($c);
curl_close ($c);

OR, if your key has the spaces:

 $encodedKey = urlEncode("first name");
    $c = curl_init();
    curl_setopt($c, CURLOPT_URL, 'http://www.mydomain.com/test.php');
    curl_setopt($c, CURLOPT_POST, true);
    curl_setopt($c, CURLOPT_POSTFIELDS , $encodedKey . "=Bobby");
    curl_exec ($c);
    curl_close ($c)
