What are some best practices for managing script inclusion and memory usage in PHP development?

To manage script inclusion and memory usage in PHP development, it is important to only include necessary scripts, optimize code to reduce memory usage, and use caching techniques where applicable. 

// Example of managing script inclusion and memory usage in PHP
// Only include necessary scripts
require_once 'config.php';
require_once 'functions.php';

// Optimize code to reduce memory usage
$largeArray = range(1, 1000000); // Consumes a lot of memory
unset($largeArray); // Free up memory by unsetting large arrays

// Use caching techniques where applicable
$cacheKey = 'data_from_database';
if (!($data = apc_fetch($cacheKey))) {
    $data = fetchDataFromDatabase();
    apc_store($cacheKey, $data, 3600); // Cache data for 1 hour
}

// Function to fetch data from database
function fetchDataFromDatabase() {
    // Database query to fetch data
    return $data;
}
