i got 2 Problems . 我有2个问题。
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。
