What are the advantages of storing numerical values as integers rather than strings in a MySQL database for PHP applications?

Storing numerical values as integers rather than strings in a MySQL database for PHP applications can lead to better performance and efficiency. Integer values take up less storage space compared to strings, resulting in faster data retrieval and processing. Additionally, performing arithmetic operations on integers is more straightforward and accurate compared to working with strings. 

// Example of storing numerical values as integers in a MySQL database
$int_value = 10;

// Connect to MySQL database
$mysqli = new mysqli("localhost", "username", "password", "database");

// Insert integer value into database
$query = "INSERT INTO table_name (int_column) VALUES ($int_value)";
$mysqli->query($query);

// Retrieve integer value from database
$result = $mysqli->query("SELECT int_column FROM table_name");
$row = $result->fetch_assoc();
echo $row['int_column'];
