What are the best practices for filtering and outputting specific elements from arrays in PHP?

When working with arrays in PHP, it is common to need to filter out specific elements based on certain criteria and then output the remaining elements. One way to achieve this is by using array_filter() function to filter the array based on a callback function that defines the criteria for inclusion. After filtering, you can use a loop to output the desired elements from the filtered array.

// Sample array
$numbers = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10];

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

// Output the filtered numbers
foreach($filteredNumbers as $num) {
    echo $num . " ";
}
