Send mail if specific condition-CodePudding

I am working on a small project but I am facing issue which I cannot solve by myself. Long story short: I have a MariaDB database with a lot of information inside and I am printing this information in frontedn in table:

code here:

<center> <table id="table_id" >

    <tr>
        <th>Номер</th> <th>Статус</th> <th>Найменование</th> <th>Сериен номер</th> <th>Локация</th> <th>Отговорник</th> <th>Калибриран на</th> <th>Следваща калибрация</th> <th>Калибрира се при</th> <th>Интервал</th> <th>Оставащи дни</th> <th>Действия</th>
    </tr>
    <?php
    
    while($user_data = mysqli_fetch_array($result)) 
{
    echo "<tr>";
    echo "<td>".$user_data['toolnr']."</td>";
    echo "<td>".$user_data['status']."</td>";
    echo "<td>".$user_data['toolname']."</td>";
    echo "<td>".$user_data['serial']."</td>";
    echo "<td>".$user_data['usedat']."</td>";
    echo "<td>".$user_data['owner']."</td>";
    echo "<td>".$user_data['calibrated']."</td>";
    echo "<td>".$user_data['nextcalibration']."</td>";
    echo "<td>".$user_data['vendors']."</td>";
    echo "<td>".$user_data['lifetime']."</td>";
    echo "<td>";
    $toolnqkakav = $user_data['toolnr'];
    $days=$user_data['days'];
    if($days <= 30){
        echo "<span style='color:red;'>$days</span>";
    }
    else{
        echo "<span style='color:green;'>$days</span>";
    }
    echo "</td>";
    echo "<td><a href='edit.php?id=$user_data[id]'><img src='img/edit.png' ></a> | <a href='delete.php?id=$user_data[id]' onclick='return checkDelete()'><img src='img/delete.png'></a></td></tr>";

So I want to make "mail function" in this case as follow: If for some of the records:

`$days <= 30; // to send email to the $owner of this record.`

I have tryed this:

`if ($days<=30)
{
ini_set('SMTP', "smtp.server.int");
ini_set('smtp_port', "25");
ini_set('sendmail_from', "[email protected]");
$to_email = "[email protected]";
$subject = "The period is expiring";
$body = "Tool ".$toolnr." expiring ";
$headers = "From: MyTools ";
 
if (mail($to_email, $subject, $body, $headers))
 
{
    echo "Email successfully sent to $to_email...";
}
 
else
 
{
    echo "Email sending failed!";
} 
}`

In this case I am getting Emails, but the goal is for every record to get separate email to the specific $owner. .Here is my query to get the data from the database:

`SELECT *, DATEDIFF(nextcalibration, CURDATE()) AS days FROM tools AS dp where isdeleted <> 'Deleted' `

Any support is higly evaluated.

And for example if $toolnr "213454" with id in the databse "23" have $days<=30 to send email to the $owner

EDIT:

Here is the full code:

    <?php
// We need to use sessions, so you should always start sessions using the below code.

session_start();
// If the user is not logged in redirect to the login page...
if (!isset($_SESSION['loggedin'])) {
     header('Location:login.html');
    exit;
}
?>

<?php
// Create database connection using config file
include_once("config.php");

// Fetch all users data from database
$result = mysqli_query($mysqli, "SELECT *, DATEDIFF(nextcalibration, CURDATE()) AS days FROM tools AS dp where isdeleted <> 'Deleted' ");

?>

When I use $toolnr and $user_data['owner'] the "system" is sending only one mail for only one record with $days<=30 not for all the tools witch are with $days<=30.

Thank you everyone the final solution is working.

while($user_data = mysqli_fetch_array($result))
