Try this simple functions

function obfuscate_email($email, $secure_param) {
list($name, $domain) = explode("@", $email);
$name = substr($name, 0, $secure_param) . str_repeat("*", strlen($name) - $secure_param);
$domain = explode(".", $domain);
$domain[0] = substr($domain[0], 0, $secure_param) . str_repeat("*", strlen($domain[0]) - $secure_param);
$domain = implode(".", $domain);
return implode("@", [$name, $domain]);
}

function obfuscate_phone_number($phone_number, $secure_param) {
return substr($phone_number, 0, $secure_param) . str_repeat("*", strlen($phone_number) - $secure_param);
}

$email = "example@domain.com";
$phone_number = "500600700";

echo obfuscate_email($email, 3) . PHP_EOL;
echo obfuscate_phone_number($phone_number, 5) . PHP_EOL;


Result

obfuscate_phone_number($phone_number, 2) . obfuscate_phone_number($phone_number, 1) .PHP_EOL;
