I have made an example here: shaquin.tk/experiments/showmore.html.

You can view the source to see all of the code behind it. The PHP code is displayed on the page.

If you don’t want to display the start string when Show more is clicked, replace the JavaScript function showMore with this:

function showMore() {
    if(state == 0) {
        state = 1;
        document.getElementById('start').style.display = 'none';
        document.getElementById('end').style.display = 'block';
        document.getElementById('showmore').innerHTML = 'Show less';
        document.getElementById('text-content').className = 'expanded';
        document.getElementById('start').className = 'expanded';
    } else {
        state = 0;
        document.getElementById('start').style.display = 'block';
        document.getElementById('end').style.display = 'none';
        document.getElementById('showmore').innerHTML = 'Show more';
        document.getElementById('text-content').className = '';
        document.getElementById('start').className = '';
    }
}

Hope this helps.
