Answer 1

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
}
?>

Answer 2

It Should be work for get your domain name and domain extension:
$email = 'test#website.edu';
$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
}

Answer 3

If .edu is the last part of the email address, you could use strlen and substr:
$email = "test#test.edu";
$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:
$strings = [
"test#test.edu",
"test#test.edu.pl",
"test#test.com"
];
foreach ($strings as $string) {
if (in_array("edu", explode(".", explode("#", $string)[1]))) {
// Etc..
}
}

Answer 4

strpos($email, ".edu."); it should be work.
for example gensek#metu.edu.tr

Answer 5

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
}
