How can PHP developers effectively separate and process IDs from checkbox values in an array?

When processing checkbox values in PHP, developers often face the challenge of separating and processing the IDs associated with the checked checkboxes from the array of checkbox values. One way to effectively handle this is by looping through the array of checkbox values and checking if each value is an ID. If it is an ID, you can process it accordingly. 

// Sample array of checkbox values
$checkboxValues = ['1', '2', '3', '4', '5'];

// Separate and process IDs from checkbox values
$ids = [];
foreach ($checkboxValues as $value) {
    if (is_numeric($value)) {
        $ids[] = $value;
        // Process the ID here or store it in another array for further processing
    }
}

// Output the IDs
print_r($ids);
