Here is the trail that I just went down.

http://www.w3.org/TR/html401/struct/links.html
lead me to here
http://www.w3.org/TR/html401/struct/global.html#adef-title
which lead me to here
http://www.w3.org/TR/html401/types.html#type-text
which lead me to here
http://www.w3.org/TR/html401/sgml/dtd.html#Text
which lead me to here
http://www.w3.org/TR/html401/types.html#type-cdata

To my final conclusion that values of attributes, although it isn't
required, should be encoded and conversely will be decoded by the client.

So, not to say that you are wrong, but I would suggest that it might be
better to explain that the example you suggested should have been
written in the following way instead.

<a href="math_operators.php" title="The &gt; Operator">The &gt;
Operator</a>

All text that gets sent to the client, that has nothing to do with
layout, should be ran through some type of cleaning & encoding method
before being sent to the client.

Just my 2pennies...

Hey Ash,
I did as you suggested and still got the same results.

Results:
'You can logon here: href="http://website.com/shop/
index.php?username='.$username.'">http://website.com/shop/index.php?
username='.$username.'. This link will take you to your web
browser to login.'.$eol;
Could it be because there is a "?" in the string or the php variable?
