Write some Software

Hello, We need 2 small changes to a PHP script that contains a form. 1. Add a button under the form that converts a field's text to a list of words. If we paste a long text and we click on this button, all the spaces should be replaced by line breaks. 2. The script executes a PHP function for the field's content, we want the same function to be called for each line instead of the whole field so if we have 10 lines, the function will be called 10 times, one for each line when validating the form. Thank you.
