What is the best practice for comparing loop results with a MySQL database in PHP?

When comparing loop results with a MySQL database in PHP, it is best practice to fetch the results from the database and store them in an array. Then, loop through the array to compare each result with the loop results. This ensures efficient comparison and minimizes the number of database queries. 

// Fetch results from MySQL database
$query = "SELECT * FROM table";
$result = mysqli_query($connection, $query);
$data = [];
while ($row = mysqli_fetch_assoc($result)) {
    $data[] = $row;
}

// Loop through results and compare with database
foreach ($loopResults as $result) {
    foreach ($data as $dbResult) {
        if ($result['column'] == $dbResult['column']) {
            // Perform actions if match found
        }
    }
}
