mcrypt_decrypt() 错误更改密钥大小
mcrypt_decrypt():此算法不支持大小为 15 的密钥.仅支持大小为 16、24 或 32 的键
mcrypt_decrypt(): Key of size 15 not supported by this algorithm. Only keys of sizes 16, 24 or 32 supported
我该如何解决这个问题?我的密钥已设置 - 无法更改.它必须是本地更改，我认为我本地的 PHP 版本对于我加载的项目来说太高级了.我该如何解决这个问题?
How Can I fix this issue? my key is set - can not change it. It has to be a local change, I think my local PHP version is too advanced for the project I loaded. How can I fix this?
推荐答案
你更新到 5.6 了吗?它说
Did you update to 5.6? It says
不再接受无效的密钥和 iv 大小.如果输入无效，mcrypt_decrypt() 现在将抛出警告并返回 FALSE.以前的键和 IV 用 '' 字节填充到下一个有效大小.
Invalid key and iv sizes are no longer accepted. mcrypt_decrypt() will now throw a warning and return FALSE if the inputs are invalid. Previously keys and IVs were padded with '' bytes to the next valid size.

阅读该引用的最后一行，您将在那里找到您的解决方案:)
Read the last line of that quote, and there you will find your solution :)

这意味着您需要用 填充您的密钥(这是以前版本为您所做的)
That means you need to pad your key with (that's what previous versions were doing for you)
$key=$key."";
