求大侠把如下两个加解密的函数转换成PHP语言
public void ENCODE()
{
byte[] byKey = null;
byte[] IV = { 0x11, 0x12, 0x13, 0x14, 0x15, 0x16, 0x17, 0x18 };
try
{
byKey = System.Text.Encoding.UTF8.GetBytes(this.encryptKey.Length > 8 ? this.encryptKey.Substring(0, 8) : this.encryptKey);
DESCryptoServiceProvider des = new DESCryptoServiceProvider();
byte[] inputByteArray = Encoding.UTF8.GetBytes(this.inputString);
MemoryStream ms = new MemoryStream();
CryptoStream cs = new CryptoStream(ms, des.CreateEncryptor(byKey, IV), CryptoStreamMode.Write);
cs.Write(inputByteArray, 0, inputByteArray.Length);
cs.FlushFinalBlock();
this.outString = Convert.ToBase64String(ms.ToArray());
}
catch (System.Exception error)
{}
}public void DECODE()
{
byte[] byKey = null;
