This is a further supplement to my posts Decoding eval gzinflate base64_decode and Decoding eval gzinflate base64_decode str_rot13.

To decode files obfuscated by SourceCop that look roughly like this:
<?php $_F=__FILE__;$_X='encoded text';eval(base64_decode('pointless crud')); ?>

I might make an automated script to decode this sort of thing and post it up on this blog once I have some free time. For now though just copy the text in between:
<?php $_F=__FILE__;$_X='
and
';eval(base64_decode('encrypted junk')); ?>";

Then paste it into the $contents variable in the code below:

<?php
$contents = "in-between text goes here (e.g. 3e4jf+jFTYhf=)";
$contents = base64_decode($contents);
$contents = "<textarea rows=\"6\" cols=\"25\">".strtr($contents, "123456aouie", "aouie123456")."</textarea>";
echo $contents;
?>

Execute the code by saving it as a file (e.g. decode.php) and visiting it in your web browser. The code inside the textarea is the original text of the file.
