php reCaptcha file_get_contents(): SSL operation failed?

$secret = 'Your google secret';
$captcha = trim( $_POST['g-recaptcha-response'] );
$url = "{$secret}&response={$captcha}&remoteip={$ip}";

        'cafile'            => '/path/to/cacert.pem',
        'verify_peer'       => true,
        'verify_peer_name'  => true,
$context = stream_context_create( $options );
$res=json_decode( file_get_contents( $url, FILE_TEXT, $context ) );
if( $res->success ){/* all good */}
else{ /* captcha failed */ }

However, with respect to the Google reCatcha API you might need to specify additional parameters to the file_get_contents function call, notably setting the context options specifically for SSL.

If you don't already have a copy of cacert.pem or ca-bundle.crt you can download them from their respective links. The path to the cafile can use either - save a copy to your host and correct the path to suit your environment.

In response to your last comment I realise you cannot change Google's reCaptcha api - what I meant was simply to do a file_get_contents actually on ( it does exist ) as a test to see if you can retrieve any content using that method as some webhosts disable the associated functionality.

change the arrayname from http to ssl and adding the cert locally made it work, thank you .. look over at my next question about pass the params with a POST request ...
