How can PHP beginners ensure that their scripts are resource-efficient when dealing with large amounts of data?

PHP beginners can ensure their scripts are resource-efficient when dealing with large amounts of data by using techniques like pagination, indexing database columns, and optimizing queries. By breaking down data into smaller chunks, limiting the number of records fetched at a time, and utilizing caching mechanisms, they can prevent memory exhaustion and improve overall performance. 

// Example of implementing pagination in PHP to handle large amounts of data
$page = isset($_GET['page']) ? $_GET['page'] : 1;
$limit = 10;
$offset = ($page - 1) * $limit;

$query = "SELECT * FROM table_name LIMIT $limit OFFSET $offset";
// Execute query and display results
