Para poder usar recaptcha necesitamos registrarnos para que nos prooporcionen una public key y una private key nos damos de alta aqui
Despues de tener las keys debemos de descargar la libreria de aqui
la incluimos en nuestro documento
1
2
3
| <?php
require_once("recaptchalib.php");
?> |
Debemos de utilizar la funcion “recaptcha_get_html()” para poder imprimirel captcha, en esta funcion consta de los siguientes parametrso: $publickey (proporcionada al registro), is_valid (verifica si el captcha es correcto), erro (muestra un error si no es correcto), quedaria de la siguiente manera:
1
2
3
4
| <?php
$captcha = recaptcha_get_html($publickey);
echo $captcha;
?> |
Para poder validar nuestro captcha haremos uso de la funcion “recaptcha_check_answer()” que es donde usaremos nuestra private key, esta funcion requiere de los siguientes parametros: $privatekey (porporcionada al registro), $remoteip (la ip remota), $challenge (un campo del captcha) y $response (un campo oculto del captcha), esta funcion quedaria de la siguiente manera:
1
2
3
4
5
6
| <?php
$check = recaptcha_check_answer($privatekey,
$remoteip = $_SERVER['REMOTE_ADDR'],
$challenge = $_POST['recaptcha_challenge_field'],
$response = $_POST['recaptcha_response_field']);
?> |
La validacion quedaria asi:
1
2
3
4
5
6
7
| <?php
if($check->is_valid) {
echo "Captcha is correct";
} else {
echo $check->error;
}
?> |
El documento completo seria asi:

Sin nada que hacer andaba viendo un rato twitter.
Para hacer conectarnos al servidor vamos a usar cURL:
1

9
| <?php
$connect = curl_init();
curl_setopt($connect, CURLOPT_URL, $url);
curl_setopt($connect, CURLOPT_VERBOSE, 0);
curl_setopt($connect, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($connect, CURLOPT_USERPWD, "$user:$pass");
curl_setopt($connect, CURLOPT_CONNECTTIMEOUT, 5);
$show = curl_exec($connect);
?> |
Despues de esto Twitter nos presta varios metodos para poder mostrar: friends, followers, twetts, timeline, etc.
http://twitter.com/statuses/friends.xml
http://twitter.com/statuses/followers.xml
http://twitter.com/statuses/public_timeline.xml
La funcion completa seria esta:

| <?php
function connect2twitter($url, $user, $pass)
{
$connect = curl_init();
curl_setopt($connect, CURLOPT_URL, $url);
curl_setopt($connect, CURLOPT_VERBOSE, 0);
curl_setopt($connect, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($connect, CURLOPT_USERPWD, "$user:$pass");
curl_setopt($connect, CURLOPT_CONNECTTIMEOUT, 5);
$show = curl_exec($connect);
if ($show) {
echo $show;
}
}
connect2twitter("http://twitter.com/statuses/friends_timeline.xml", "tuuser", "tupass");
?> |
