How can developers efficiently select specific elements from a list in PHP?

Developers can efficiently select specific elements from a list in PHP by using array functions such as array_filter() or array_map(). These functions allow developers to apply a callback function to each element in the array and return only the elements that meet certain criteria. By using these functions, developers can easily filter out elements based on specific conditions without having to iterate through the entire list manually.

// Example of filtering elements from a list in PHP
$numbers = [1, 2, 3, 4, 5];

// Select only even numbers
$evenNumbers = array_filter($numbers, function($num) {
    return $num % 2 == 0;
});

print_r($evenNumbers); // Output: [2, 4]
