UNIX - How can I highlight file content with pattern in another file?

Question

I want to use grep --color -E '^|pattern1|pattern2' file name for highlight parts of my file, but patterns are in another files. for example:

base file:

#!/usr/bin/env
<?php 
include 'second.php';
function saybye()
{
    return "bye";
}
echo "<br />";
function sayHello() {
   return "hellobye";
}
?>

pattern file:

#!/usr/bin/env
<?php 
include 'second.php';
function saybye()
{
    return "bye";
}
echo "<br />";
?>

I want to highlight parts of base file that exact match with pattern file.

also I want to highlight lines with different colors. how can I do this?

thanks for any help.
