How can PHP scripts handle multiple users accessing the database simultaneously?

When multiple users are accessing the database simultaneously, PHP scripts can handle this by implementing database connection pooling. This involves creating a pool of database connections that can be shared among multiple users, reducing the overhead of opening and closing connections for each user. By using connection pooling, PHP scripts can efficiently manage database connections and handle multiple users accessing the database simultaneously. 

// Create a database connection pool
$connectionPool = new SplObjectStorage();

// Function to get a database connection from the pool
function getConnectionFromPool() {
    global $connectionPool;
    
    foreach ($connectionPool as $connection) {
        $connectionPool->detach($connection);
        return $connection;
    }
    
    // If no available connections, create a new one
    $connection = new mysqli('localhost', 'username', 'password', 'database');
    return $connection;
}

// Function to return a database connection to the pool
function returnConnectionToPool($connection) {
    global $connectionPool;
    
    $connectionPool->attach($connection);
}

// Example of using the connection pool
$connection1 = getConnectionFromPool();
// Use connection for database operations
returnConnectionToPool($connection1);
