What are the advantages of using SQL Views in PHP applications for database data retrieval and presentation?

When working with database data in PHP applications, using SQL Views can provide several advantages. Views can simplify complex queries by encapsulating them into a single entity, making the code more readable and maintainable. They can also improve performance by pre-computing and storing the results of frequently used queries. Additionally, views can enhance security by restricting access to specific columns or rows of a table. 

// Example of using a SQL View in PHP to retrieve and display data from a database

// Connect to the database
$pdo = new PDO('mysql:host=localhost;dbname=mydatabase', 'username', 'password');

// Create a SQL View to encapsulate a complex query
$sql = "CREATE VIEW view_name AS
        SELECT column1, column2
        FROM table
        WHERE condition";

$pdo->exec($sql);

// Query the SQL View to retrieve data
$query = $pdo->query("SELECT * FROM view_name");

// Display the results
while ($row = $query->fetch(PDO::FETCH_ASSOC)) {
    echo $row['column1'] . ' - ' . $row['column2'] . '<br>';
}

// Close the database connection
$pdo = null;
