IIRC eval starts in <?php context so if you have a complete webpage
including code then do:
eval("?>$page<?php");

I couldn't get eval to work with my example :(

So I made a function to eval my example :)

Hope it can help the OP

=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
<code language="php" length="41 lines">
<?php
$db_value = '<b><?php echo phpversion(); ?></b>
foobar
<?php $x=date("Y-m-d"); ?>
foobaz
<?php echo $x; ?>
foobar again';

echo code_eval($db_value);
echo "\n--------\n";
eval("?>$db_value<?php"); ## error here!

function code_eval($__STO_string) {
## __STO_ (security through obscurity)

// isolate all code between the php tags
preg_match_all('/<\?php(.*)\?>/Us', $__STO_string, $__STO_php_code);

// eval each one of them and store each evaluation in an array
$__STO_evaled = array();
foreach ($__STO_php_code[1] as $__STO_sub_code) {
ob_start();
eval($__STO_sub_code);
$__STO_evaled[] = ob_get_clean();
}

// replace code and php tags by their result
$__STO_i = 0;
$__STO_string_evaled = $__STO_string;
while (isset($__STO_evaled[$__STO_i])) {
$__STO_string_evaled = preg_replace('/<\?php(.*)\?>/Us',
$__STO_evaled[$__STO_i],
$__STO_string_evaled,
1);
++$__STO_i;
}

// return the eval'd chunk
return $__STO_string_evaled;
}
?>

Another way to do this is through remote include(). Use an URL in
place of a file path like this:

include("http://localhost/db_php_code.php?criteria=something");

In db_php_code.php, connect to the database and echo the code.
