What are some best practices for managing data retrieval and storage in PHP to prevent performance issues when working with large datasets?

When working with large datasets in PHP, it's important to use efficient data retrieval and storage methods to prevent performance issues. One best practice is to use pagination to limit the amount of data retrieved at once, reducing memory usage and speeding up queries. Additionally, utilizing indexes on database columns can improve query performance when retrieving data. 

// Example of using pagination to limit data retrieval
$page = isset($_GET['page']) ? $_GET['page'] : 1;
$limit = 10;
$offset = ($page - 1) * $limit;

$query = "SELECT * FROM large_table LIMIT $limit OFFSET $offset";
// Execute the query and process the results

// Example of creating an index on a database column
$pdo->exec("CREATE INDEX idx_column_name ON large_table (column_name)");
