This function works fine for me.

function isEmailEdu($email){
  $pattern = '/@.*\.edu(\.[a-z]{2,})?$/';
  if (preg_match($pattern, $email)) {
    return true;
  }
  return false;
}

If .edu is the last part of the email address, you could use strlen and substr:

$email = "[email protected]";
$end = ".edu";
$string_end = substr($email, strlen($email) - strlen($end));
if ($end === $string_end) {
    // Ok
}

Maybe it is also an option to use explode and split on @. Then use explode again and split on a dot and check if the array returned contains edu:

$strings = [
    "[email protected]",
    "[email protected]",    
    "[email protected]"
];
foreach ($strings as $string) {
    if (in_array("edu", explode(".", explode("@", $string)[1]))) {
        // Etc..
    }
}

It Should be work for get your domain name and domain extension:

 $email = '[email protected]';
$getDomain = explode('@', $email);
$explValue = explode('.', $getDomain[1], 2);
print_r($explValue);

The out put is:

Array ( [0] => website [1] => edu )

After that you can check with 

if($explValue[1] == 'edu'){
//your code here
}

You can use substr And get last 4 characters if this is valid as per your requirement so the email is valid else it not. 

$string = "xyzasd.edu";
echo $txt = substr($string,-4);

if($txt == ".edu"){
    //Valid
}else{
    //Not Valid
}

You just need to make a substring including the last 3 chars of the current string.

<?php
$tld = substr($email, strlen($email)-2, 3);    // three last chars of the string
if ($tld = "edu") {
    // do stuff
}
?>
