php - 简单一：php爆炸不输出预期结果

Question

好的，所以对于这个简单的 php 函数：

$FBIDs = "1,15,16,18,30";
$FBArr = explode(",", $FBIds);

print_r($FBArr);

输出是：

Array ( [0] => )

难道我做错了什么？我瞎了吗？为什么这不给我一个以数字为元素的数组？这让我发疯了！

Answer 1

The variable you're trying to explode is $FBIDs, but you're exploding $FBIds; The final "d" needs to be capitalized and it should work.
