Solution:

You just need to use parameters with prepared statements

<?php
    $LoggedInUser = $_SESSION['user'];
    $stmt = $dbh->prepare("SELECT * FROM Logs WHERE user_email = ? ORDER BY log_id ASC");
    $stmt->execute([$LoggedInUser]);
    if ($stmt->rowCount() == 0) {
        echo 'Log history are empty.';
    } else {
        // Data we collected from the registered user
    }
?>
