Or, if you don't want to mess with php, then you need to convert the < and > symbols to their html equivalents - then the page will show the code not a link.
So, to display:<a href="mylink">Link text</a>
you need the following on your page:
<a href="mylink">Link text</a>
You'll see that < is replaced by < and > by > (less than and greater than symbols)
