Base 64 decode

[smush]

Hi

I'm trying to decode a file that has been based 64'd 50 times. I started out ensuring the php script and the file to be decoded are in the same location. After that I got the contents of the file then set up a while loop to go through 50 times running 'base_64 decode' on the file after that I tried to echo the file but I get I feel whatever is missing will be pretty obvious once it is pointed out. Thanks.

<?php
$content =  file_get_contents("b64.txt");
$x = 0;

while($x < 50) {
$input = base64_decode ($content);
	$x++;
}
echo $input;

?>

You're always decoding the same value since you always pass $content to the function. Try this

<?php
$input =  file_get_contents("b64.txt");
$x = 0;

while($x < 50) {
$input = base64_decode ($input);
	$x++;
}
echo $input;

?>

Thanks it seems so obvious now!
