Is it considered good practice to pass individual array elements as parameters to a PHP function, or is it better to pass the entire array and extract the elements within the function?

It is generally considered better practice to pass the entire array as a parameter to a PHP function rather than passing individual array elements. This is because passing the entire array allows for more flexibility and scalability in the function, as it can easily handle arrays of different lengths without needing to modify the function signature. Within the function, you can then extract the individual elements as needed. 

// Passing the entire array as a parameter to a PHP function
function processArray($arr) {
    foreach ($arr as $element) {
        // Process each element as needed
        echo $element . "\n";
    }
}

// Example usage
$array = [1, 2, 3, 4, 5];
processArray($array);
