php相当于以下sha1加密c＃代码

Question

I have tried converting the following c# code for sha1 password encryption check to a PHP version, but seem to be failing:

As this code goes in my understanding-> 1) Encode into ASCII 2)Stores in byte array 3) encrypt that byte array into sha1 and stores into again in byte array new byte[60] 4)converts that byte array in 64 bit string. I am not able to get the byte string part in following code.

 private static string ComputeHas(byte[] arry){

    StringBuilder sb = new StringBuilder(arry.Length);
    return Convert.ToBase64String(arry);
}
public static string SHA1HashEncode(string pwd)
{
    SHA1 sh = new SHA1CryptoServiceProvider();
    byte[] arr = new byte[60];
    string hash = "";
    byte[] array = Encoding.ASCII.GetBytes(pwd);
    arr = sh.ComputeHash(array);
    hash = ComputeHas(arr);
    return hash;
}

Here is what I tried:

//convert string to ascii 
for($i = 0; $i < mb_strlen($pwd, 'ASCII'); $i++) {

$pwd1=ord($pwd[$i]); 
} 

//sha1 encryption of password 
$pwd2=sha1($pwd1);

What i have tried so far to get possible exact is following: //convert string to ascii

for($i = 0; $i < mb_strlen($pwd, 'ASCII'); $i++)
{
    $pwd1=ord($pwd[$i]);
    $pwd2[]=$pwd1; 
}

//convert array to string
$pwdString = serialize($pwd2);

//compute hase of string
$pwdHash= array();
$pwdHash[]=array_fill(0,60,sha1($pwdString));

$pwdHashString=serialize($pwdHash);

//convert to 64 bit string encodeing

$pwd64encode=base64_encode($pwdHashString);
print_r($pwd64encode);

But i am not getting exact out of C# code in php.

From PHP's documentation about SHA1

$variable = sha1("input");
