Are there any specific considerations to keep in mind when using array_unshift in PHP for form data manipulation?

When using array_unshift in PHP for form data manipulation, it's important to remember that this function will add elements to the beginning of an array, shifting the existing elements to higher indices. This can affect the order in which form data is processed or displayed. To ensure that the form data remains in the correct order, consider using array_push to add elements to the end of the array instead.

// Example of using array_push to add form data to an array
$form_data = [];
array_push($form_data, $_POST['field1']);
array_push($form_data, $_POST['field2']);
array_push($form_data, $_POST['field3']);
