Message dialog if PHP function successful or not - php

Question

I have a PHP function that checks some data before inserting it into the DB.
For now I have thees messages that inside my php function that display, wherever I am calling the function. ex: div.
I would like instead of the small message inside the div, to have a message box that will display the message. How can I do this? Thanks
if($u_l_name == $dbuser_last_name and $u_name == $dbuser_first_name)
{
echo "Record Exists Already";
}
else
{
$stmt2 = $this->link->prepare("INSERT INTO employers (user_password, user_first_name, user_last_name, user_DOB, user_address, user_email, user_phone, user_gender, user_position, user_contract_type, user_contract_hours) VALUES (?,?,?,?,?,?,?,?,?,?,?)");
$stmt2->bind_param("ssssssssssi", $u_password, $u_name, $u_l_name, $u_DOB, $u_address, $u_email, $u_phone, $u_gender, $u_position, $u_contract_type, $u_contract_hours);
$stmt2->execute();
$stmt2->close();
echo "Record Added Succesfully";
}
Function call:
<?php
if(isset($_POST['submitButton']))
{
$admin_query->addEmployerData($u_password, $u_name, $u_l_name, $u_DOB, $u_address, $u_email, $u_phone, $u_gender, $u_position, $u_contract_type, $u_contract_hours);
}
?>

Do you mean Javascript alert method? if yes here is how you can do it:
$message;
if($u_l_name == $dbuser_last_name and $u_name == $dbuser_first_name)
{
$message = "Record Exists Already";
}
else
{
$stmt2 = $this->link->prepare("INSERT INTO employers (user_password, user_first_name, user_last_name, user_DOB, user_address, user_email, user_phone, user_gender, user_position, user_contract_type, user_contract_hours) VALUES (?,?,?,?,?,?,?,?,?,?,?)");
$stmt2->bind_param("ssssssssssi", $u_password, $u_name, $u_l_name, $u_DOB, $u_address, $u_email, $u_phone, $u_gender, $u_position, $u_contract_type, $u_contract_hours);
$stmt2->execute();
$stmt2->close();
$message = "Record Added Succesfully";
}
echo "<script>alert('$message')</script>";
