What are the advantages of splitting a table into multiple tables for counting entries in PHP?

When dealing with a large dataset, splitting a table into multiple tables can improve performance when counting entries in PHP. By dividing the data into smaller, more manageable chunks, queries can be executed more efficiently, resulting in faster response times. Additionally, this approach can help with organizing and structuring the data in a more logical way, making it easier to work with and maintain. 

// Example of splitting a table into multiple tables for counting entries in PHP

// Create connection to database
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "myDB";

$conn = new mysqli($servername, $username, $password, $dbname);

// Check connection
if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
}

// Query to count entries in multiple tables
$sql = "SELECT (SELECT COUNT(*) FROM table1) + (SELECT COUNT(*) FROM table2) AS total_count";
$result = $conn->query($sql);

if ($result->num_rows > 0) {
    // Output data of each row
    while($row = $result->fetch_assoc()) {
        echo "Total count: " . $row["total_count"];
    }
} else {
    echo "0 results";
}

// Close connection
$conn->close();
