base64_decode returns binary data

the base64_decode() returns data in binary!

ive tried to display the output from base64_decode($handshake) and i get binary??

is there someother function that can convert the decoded data in readable data so i can compare it in my code below?

<?php
$handshake = '';
$handshake = trim($_GET['handshake']);

if("xyz" == base64_decode($handshake))
      echo "Handshake OK";
else
      echo "HACKING ATTEMPT";
?>

Is it serialized perhaps? Normally the function returns the decoded string, so that's weird...
What is it you encode...
Can you show us the whole cycle? SO, both the encoding and decoding part?

OK, example:

<?php
$str = 'secret';
$encoded_str = base64_encode($str);
if("secret" == base64_decode($encoded_str))
     echo "OK";
else
     echo "HACKING ATTEMPT";
?>

will fail as base64_decode() return binary data.  How can i decode a string encrpyted by base64?

see another example:

<?php
$encoded_str = "KHvCoxP73EqvnVaCubzwUQ==";
echo "<p>".$encoded_str."</p>";
$decoded_str = base64_decode($encoded_str);
echo "<p>".$decoded_str."</p>";
?>

output:

KHvCoxP73EqvnVaCubzwUQ==

The $encoded_str value is a string encoded using a base64 algorithm sent in the URL....
