In PHP, traits are a mechanism for code reuse and can be used to sort them using Composer's autoloading functionalities.
// Autoload the Composer dependencies
require 'vendor/autoload.php';
// Define the traits
trait Sortable {
public function sortArray($array) {
sort($array);
return $array;
}
}
trait Filterable {
public function filterArray($array, $callback) {
return array_filter($array, $callback);
}
}
// Example class using traits
class Example {
use Sortable, Filterable;
public function sortAndFilter($array, $callback) {
$sortedArray = $this->sortArray($array);
return $this->filterArray($sortedArray, $callback);
}
}
// Usage example
$example = new Example();
$inputArray = [5, 3, 8, 1];
$callback = function($item) {
return $item > 3; // Filter condition
};
$result = $example->sortAndFilter($inputArray, $callback);
print_r($result); // Output: Array ( [0] => 5 [1] => 8 )
