How can the efficiency of sorting arrays in PHP be improved to handle large datasets?

When sorting large datasets in PHP, the efficiency can be improved by using built-in sorting functions like `sort()` or `asort()` instead of custom sorting algorithms. These built-in functions are optimized for performance and can handle large arrays more efficiently.

// Example of sorting a large array efficiently using built-in functions
$largeArray = range(1, 1000000); // Generating a large array of numbers

// Using the built-in sort function to efficiently sort the array
sort($largeArray);

// Output the sorted array
print_r($largeArray);
