//edit the permissions needed
$permsneeded='publish_stream,user_photos';

else {
    $loginUrl = $fb->getLoginUrl(array(
                'scope' => $permsneeded,
                ));

    echo "

$signed_request = $_REQUEST["signed_request"];

list($encoded_sig, $payload) = explode(".", $signed_request, 2); 
$data = json_decode(base64_decode(strtr($payload, "-_", "+/")), true);

this is "$image = $images[ rand(0,(count($images)-1)) ];" 这是“ $ image = $ images [rand（0，（count（$ images）-1））]”； is not working some time . 一段时间没有工作。 it is didn't get image for imagecreatefromjpeg 它没有获得imagecreatefromjpeg的图像

Answer 1

Try like this and please avoid the blank statements. 尝试这样，请避免使用空白语句。

if(!($me)) 
{
    echo '<script> top.location.href="'.$facebook->getLoginUrl(array(
                    'req_perms' => $permsneeded,
                    'next' =>'https://apps.facebook.com/246435698815637/',
                    )). '";
          </script>';
    exit();
}

and second one is correct,it should work,but i don't get your point about imagecreatefromjpeg as you don't give any information about it.Paste your code where you have use that function. 第二个是正确的，它应该可以工作，但是我不明白关于imagecreatefromjpeg的观点，因为您没有提供任何有关它的信息。将您的代码粘贴到使用该函数的位置。
