有没有同时懂 C#和 PHP 的大佬，帮看下 C#这段 aes 解密代码怎么翻译成 PHP 的好？

[UnrealEngine]

public static string AESDecrypt(string text, string key, string iv)
{
var result = string.Empty;
if (key.Length != 16 || iv.Length != 16)
{
return result;
}
var encryptBytes = System.Convert.FromBase64String(text);
var aes = System.Security.Cryptography.Aes.Create();
aes.Mode = System.Security.Cryptography.CipherMode.CBC;
aes.Padding = System.Security.Cryptography.PaddingMode.PKCS7;
aes.Key = System.Text.Encoding.UTF8.GetBytes(key);
aes.IV = System.Text.Encoding.UTF8.GetBytes(iv);
var transform = aes.CreateDecryptor();
result = System.Text.Encoding.UTF8.GetString(transform.TransformFinalBlock(encryptBytes, 0, encryptBytes.Length));
return result;
}

@littleylv 不行，哦忘了那个方法加密前还有另一个处理函数，

字符串：FHPdyFl63G6xl/2rge/VQDkCW79tNG4cAFlnulZHj2shQ1+m1GeY++7MdTX/+KD9/13vDremaHrSMRlg1Wd/HA==

KEY：1805412879961850

public static string AESDecrypt(string cipherText, string key)
{
var iv = string.Join("", key.ToCharArray().Reverse());
return AESDecrypt(cipherText, key, iv);
}

你是一点都不懂 C#还是一点都不懂 PHP 还是都不懂
我都方法告诉你了，就算你前面有个处理函数，不就是把 key 反转成 iv 吗

$input = base64_decode('FHPdyFl63G6xl/2rge/VQDkCW79tNG4cAFlnulZHj2shQ1+m1GeY++7 MdTX/+KD9/13vDremaHrSMRlg1Wd/HA==');
$key = '1805412879961850';
$iv = strrev($key);
$decrypted = openssl_decrypt($input, 'AES-128-CBC', $key, OPENSSL_RAW_DATA, $iv);
var_dump($decrypted); // 打印结果：string(49) "{"ActionId":1000,"SourceName":"YF37ZTOVEN6NRZO3"}"
