You could make a new function
function eval2($code) {
eval('?>' . $code . '<?PHP');
}
This way eval2() should take the code as it usually looks in a PHP file.
<?PHP
$code="echo \"test\n\"; ?> <h1>hello</h1> <?PHP echo \"test2\n\"; ";
eval($code);
?>
would become
<?PHP
$code="<?PHP echo \"test\n\"; ?> <h1>hello</h1> <?PHP echo \"test2\n\"; ?>";
eval2($code);
?>
(I haven't tested this one, but in theory it should work).
