The way I understand it, you want to have new textboxes appear due to an onClick event attached to a button. If that is incorrect, please clarify the post a bit.
To proceed with my understanding, let me preface: You will not need PHP to accomplish this task. A little CSS and Javascript will do the trick.

    /* Sets class for the text box with a visible property */
    .show {
