是否可以从php代码调用facebook共享？我的意思是，当任何用户点击我网站上的图片时，我都想分享他的脸书账户上的图片。有可能吗？那我们该怎么做呢？
提前感谢

是的，这是可能的。以下是来自的示例代码http://developers.facebook.com/docs/reference/php/facebook-api/
这是为了将照片上传到用户配置文件。
<?
// Remember to copy files from the SDK's src/ directory to a
// directory in your application on the server, such as php-sdk/
require_once('php-sdk/facebook.php');
$config = array(
'appId' => 'YOUR_APP_ID',
'secret' => 'YOUR_APP_SECRET',
'fileUpload' => true,
);
$facebook = new Facebook($config);
$user_id = $facebook->getUser();
$photo = './mypic.png'; // Path to the photo on the local filesystem
$message = 'Photo upload via the PHP SDK!';
?>
<html>
<head></head>
<body>
<?
if($user_id) {
// We have a user ID, so probably a logged in user.
// If not, we'll get an exception, which we handle below.
try {
// Upload to a user's profile. The photo will be in the
// first album in the profile. You can also upload to
// a specific album by using /ALBUM_ID as the path
$ret_obj = $facebook->api('/me/photos', 'POST', array(
'source' => '@' . $photo,
'message' => $message,
)
);
echo '<pre>Photo ID: ' . $ret_obj['id'] . '</pre>';
} catch(FacebookApiException $e) {
// If the user is logged out, you can have a
// user ID even though the access token is invalid.
// In this case, we'll get an exception, so we'll
// just ask the user to login again here.
$login_url = $facebook->getLoginUrl( array(
'scope' => 'photo_upload'
));
echo 'Please <a href="' . $login_url . '">login.</a>';
error_log($e->getType());
error_log($e->getMessage());
}
echo '<br /><a href="' . $facebook->getLogoutUrl() . '">logout</a>';
} else {
// No user, print a link for the user to login
// To upload a photo to a user's wall, we need photo_upload permission
// We'll use the current URL as the redirect_uri, so we don't
// need to specify it here.
$login_url = $facebook->getLoginUrl( array( 'scope' => 'photo_upload') );
echo 'Please <a href="' . $login_url . '">login.</a>';
}
?>
</body>
