How can one optimize PHP code to handle large amounts of data without causing the database to crash?

To optimize PHP code to handle large amounts of data without causing the database to crash, you can implement pagination to limit the number of records fetched at a time. This way, the database won't be overloaded with a massive amount of data in a single query. Additionally, you can optimize your database queries by using indexes, optimizing joins, and avoiding unnecessary queries. 

// Example of implementing pagination in PHP to limit the number of records fetched at a time
$page = isset($_GET['page']) ? $_GET['page'] : 1;
$limit = 10;
$offset = ($page - 1) * $limit;

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