In PHP, what are the advantages of using arrays or database functions over complex if-else statements for comparing data from MySQL databases?

When comparing data from MySQL databases, using arrays or database functions in PHP can provide more efficient and organized code compared to using complex if-else statements. Arrays allow for easy storage and retrieval of data, while database functions such as `mysqli_fetch_assoc()` or `PDO::fetch()` simplify the process of fetching and comparing data directly from the database. This approach can improve code readability, maintainability, and performance.

// Using arrays to compare data from MySQL database
$data = []; // Initialize an empty array
$result = mysqli_query($conn, "SELECT * FROM table"); // Query the database
while ($row = mysqli_fetch_assoc($result)) {
    $data[] = $row; // Store each row in the array
}

// Compare data using arrays
foreach ($data as $row) {
    // Compare data here
}
