What are the best practices for optimizing array manipulation in PHP, especially when working with large datasets like dates and goals?

When working with large datasets like dates and goals in PHP, it is important to optimize array manipulation to improve performance. One way to do this is by using built-in array functions like array_map, array_filter, and array_reduce instead of looping through arrays manually. Additionally, consider using associative arrays or multidimensional arrays for better organization and easier access to data. 

// Example of optimizing array manipulation for dates and goals

// Sample array of dates
$dates = ['2022-01-01', '2022-01-15', '2022-02-01', '2022-02-15'];

// Using array_map to format dates
$formatted_dates = array_map(function($date) {
    return date('F j, Y', strtotime($date));
}, $dates);

// Sample array of goals
$goals = [
    ['title' => 'Lose Weight', 'target' => 10],
    ['title' => 'Save Money', 'target' => 500],
    ['title' => 'Read Books', 'target' => 20]
];

// Using array_reduce to calculate total targets
$total_targets = array_reduce($goals, function($carry, $goal) {
    return $carry + $goal['target'];
}, 0);

// Output formatted dates and total targets
print_r($formatted_dates);
echo "Total targets: " . $total_targets;
