Description:
------------
I have a string encrypted with mcrypt and encoded in base64. I unbase64 this string and I decrypt it using mcrypt. I got the exact same string but when I try to explode it into an array with the explode() function, I cannot make comparison == with the last element of the newly created array.

Reproduce code:
---------------
$key = "validkey";
$input = base64_decode($txtEncrypted);	
$decrypted = mcrypt_ecb(MCRYPT_RIJNDAEL_128, $key, $input, MCRYPT_DECRYPT);

echo $decrypted."<br>";

$array_data = explode('||', $decrypted);

echo "|".$array_data."|<br>";

if ($array_data[8] == 'end') {
   echo "it works!";
}

Expected result:
----------------
data||ddata||daata||dadta||dasta||datad||daata||datsa||end
|end|
it works!

Actual result:
--------------
data||ddata||daata||dadta||dasta||datad||daata||datsa||end
|end|
