In PHP, filtering traits using built-in functions can be efficiently done by defining methods within the traits that utilize these functions and then invoking them from the classes that use the traits.
<?php
trait Filterable {
public function filterArray(array $input) {
return array_filter($input, function($value) {
return $value > 0; // Example condition: keep only positive values
});
}
}
class Example {
use Filterable;
public function getFilteredValues($values) {
return $this->filterArray($values);
}
}
$example = new Example();
$filteredValues = $example->getFilteredValues([-1, 0, 1, 2, -2, 3]);
print_r($filteredValues);
?>
