I’ve been writing a php/html page encoder/decoder… I know it already exists but it’s a university project so go on XDDD

I encode the pages that I want to protect let’s say hypothetically with base64_encode and when I receive a request of any pages I have a loader that reads the coded page, decrypts it and with eval executes it. The real problems arise when I try to decrypt and execute a mixed php/html page. Obviously eval can’t execute html code so my question is do I really become crazy about splitting the page executing the php code and print the html? And also if I include an encoded php or php/html page do I really have to reuse the method up here?

I hope someone can really help me because i have a week left before the deadline and I can’t change the project at this point.

chris here the function and the fisrt calling in $param[0] i’ve got the filename called

function MyInclude($filename)
{
// create the temp file
$temp_filename = "tmp.php";
$handle = fopen($temp_filename , 'w+');
if (!$handle)
  die('Error creating temp file');

// write the decrypted data, close the handle
$tmp=file_get_contents($filename);

$data=MCrypt_Decode($tmp,'PFL_EPU_V100_mia');

fwrite($handle,$data );
fclose($handle);

// start output buffering to contain any output the script creates
ob_start();

try {
 include($temp_filename);
} catch (Exception $e) {
 die('There was an error in the encrypted file, cannot process');
}

// get the output, clear the buffer
$output = ob_get_contents();
ob_end_clean();

//destroy the temp file
unlink($temp_filename);

// now you can output the buffer, if desired:
echo $output;
}

MyInclude($param[0]);

the $param[0] file here

<?php
 session_start();
 $_SESSION['title']='Home';
 MyInclude("header.php");
?>

<body>
    sono il body <?php echo APP_PATH; ?>
</body>

<?
echo "boss";
 MyInclude("footer.php");
?>

any idea about it??? or you need some other code??? let me know T_T

    Is it possible to decrypt the page, write it to a file, then include it? That would let the PHP interpreter do what it does best – interpret PHP documents. That will include HTML/PHP combinations without relying on eval.

    The outline of that would be:

    // create the temp file
$temp_filename = "tmp.php";
$handle = fopen($filename , 'w');
if (!$handle)
  die('Error creating temp file');

// write the decrypted data, close the handle
fwrite($handle, $decrypted_data);
fclose($handle);

// start output buffering to contain any output the script creates
ob_start();

try {
 include_once($temp_filename);
} catch (Exception $e) {
 die('There was an error in the encrypted file, cannot process');
}

// get the output, clear the buffer
$output = ob_get_contents();
ob_end_clean();

//destroy the temp file
unlink($temp_filename);

// now you can output the buffer, if desired:
echo $output;
