Is using array_filter a more efficient alternative to using loops for filtering arrays in PHP?

Using `array_filter` is generally a more efficient alternative to using loops for filtering arrays in PHP. `array_filter` allows you to specify a callback function that determines which elements should be included in the filtered array, resulting in a more concise and readable code. It also eliminates the need for manual iteration over the array, which can improve performance. 

// Example of using array_filter to filter an array
$numbers = [1, 2, 3, 4, 5];

// Filter out even numbers
$filteredNumbers = array_filter($numbers, function($num) {
    return $num % 2 != 0;
});

print_r($filteredNumbers);
