[PHP] PHP translation needed

[Grace Shibley]

Hi Everyone,

We have an encryption function that was written in another language that we
needed translated to PHP.

Here's the function:

function rc4 pText, pKey
    -- initialize
    repeat with i = 0 to 255
        put i into S1[i]
    end repeat

    put 0 into i
    repeat with n = 0 to 255
        add 1 to i
        if i > length(pkey) then put 1 into i
        put chartonum(char i of pKey) into S2[n]
    end repeat

    put 0 into j
    repeat with i = 0 to 255
        put (j + S1[i] + S2[i]) mod 256 into j
        put S1[i] into temp
        put S1[j] into S1[i]
        put temp into S1[j]
    end repeat

    -- encrypt/decrypt
    put 0 into i ; put 0 into j
    repeat for each char c in pText
        put chartonum(c) into tChar

        put (i + 1) mod 256 into i
        put (j + S1[i]) mod 256 into j
        put S1[i] into temp
        put S1[j] into S1[i]
        put temp into S1[j]
        put (S1[i] + S1[j]) mod 256 into t
        put S1[t] into K

        put numtochar(tChar bitXor K) after tOutput
    end repeat

    return tOutput
end rc4

Can anyone help us with this?  We don't mind paying via PayPal :)

Thanks!
