decode a hex to pdf file

[rkutti]

Hi,

 

I have a pdf file content in hex encoded format. I want to decode that pdf file.

Is there any php code or tool available to do this decoding.

I used the following function to decode the hex content to pdf and tried to open the pdf file, it throws error.

 

function hexToStr($hex)

{

    $string='';

    for ($i=0; $i < strlen($hex)-1; $i+=2)

    {

        $string .= chr(hexdec($hex[$i].$hex[$i+1]));

    }

    return $string;

}

 

Please help me to decode a hex value to pdf file.

 

Thanks in advance

It will probably be helpful to take a peek at pack (likely using H* or h* depending on the 'hex encoded format').
