I think you get the correct decoded string. It looks like a compressed or encrypted file. — Felipe Alameda A, Nov 17 '12 at 07:12

I tried this code:

header('Content-disposition: filename="my.zip"');
$s = "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";
$out = base64_decode($s);
print($out);
?>

And the browser downloads a working ZIP file that contains an .xml file.

If you want to process the contents of that ZIP file using PHP, you can enable the php_zip extension and check out this answer: Unzip a file with php

Thank you. I tried the same code but it is downloading the php file itself, not a zip file — user1808669, Nov 17 '12 at 07:38
I am using Xampp localhost. the file name has extenssion as .php which is WinRAR ZIP archive (1.1 kB). After download when I double clicked on it, it is opening in editot with some special charectors loke PK [][][] — user1808669, Nov 17 '12 at 07:51
Download the file, rename it to .zip and open it with your unzipping software (or Windows built-in stuff). You can also add this to the PHP code to force the filename: `header('Content-disposition: filename="my.zip"');` — huysentruitw, Nov 17 '12 at 07:54
