c# 的sha1转成php

[zgw2014]

SHA1CryptoServiceProvider sha1 = new SHA1CryptoServiceProvider();
byte[] str1 = Encoding.UTF8.GetBytes(DecryptString);
byte[] str2 = sha1.ComputeHash(str1);
sha1.Clear();
(sha1 as IDisposable).Dispose();
return Convert.ToBase64String(str2);




上边这段代码似c# 的sha1加密方法，请问一下怎么转换成php？？？？？？？？感谢各位兄弟姐妹

 $s = base64_encode(hex2bin(sha1($DecryptString')));
