I have written a php function that decode the protected email based on this answer

Scraping of protected email

I took this function

def decodeEmail(e):

    de = ""

    k = int(e[:2], 16)



    for i in range(2, len(e)-1, 2):

        de += chr(int(e[i:i+2], 16)^k)



    return de

converted to php :

function decode($e){

$de= "";

$c = substr($e,0,2);

$k = hexdec($c);



foreach(range(2, strlen($e)-1, 2) as $i => $v){

       $s = substr($e,$i,$i+2);

       $d = hexdec($s);

       $de .= chr($d^$k);

}

return $de;

}

the function works almost except the last three characters, sometimes two, sometimes one.
sample :

given value

caaba0a3bea28af9fcfabfabaeb9e4a9a5a7

it returns

ajith@360uads���

the correct result should be

[email protected]

what did I do wrong in my function ? what did I miss from the original python function ?

My Answer:
base64.b64decode(e).decode('utf-8') return de__and converted it to php function as follows:function decodeEmail($e){ $de = base64_decode($e); return $de;}You can use this php function to decode the protected email in your scraping script.
