What are the advantages and disadvantages of using numbers instead of strings in PHP for database optimization?

When optimizing a database in PHP, using numbers instead of strings can improve performance by reducing the amount of storage space needed and making comparisons faster. However, using numbers can also make the code less readable and harder to maintain, especially when dealing with complex relationships or data transformations. 

// Example of using numbers instead of strings for database optimization
// Define constants for status values
define('STATUS_ACTIVE', 1);
define('STATUS_INACTIVE', 0);

// Insert data into the database using numbers instead of strings
$query = "INSERT INTO users (name, status) VALUES ('John Doe', " . STATUS_ACTIVE . ")";
$result = mysqli_query($connection, $query);

// Retrieve data from the database using numbers instead of strings
$query = "SELECT * FROM users WHERE status = " . STATUS_ACTIVE;
$result = mysqli_query($connection, $query);
