How can PHP developers optimize their code to efficiently extract and manipulate data from arrays, as illustrated by the examples shared in the forum thread?

To optimize code for efficiently extracting and manipulating data from arrays in PHP, developers can utilize built-in array functions like array_map, array_filter, and array_reduce. These functions can help streamline the code and make it more readable and maintainable.

// Example using array_map to manipulate data from an array
$data = [1, 2, 3, 4, 5];
$multipliedData = array_map(function($value) {
    return $value * 2;
}, $data);
print_r($multipliedData);
