SSL link WITHIN a product description or EZ Page

I normally know how to create links to ssl pages (https://...). But how do I create a link to a secure page within a product description or EZ Page? AFAICT, since the html/code is stored in the database, the php code doesn't work when the page is displayed. For example,

<php echo zen_ez_pages_link(21, 0, true, false, false); ?> or

<a href="<?php echo zen_href_link(FILENAME_CONTACT_US, '','SSL'); ?>">Contact Us </a>

They don't work b/c the php isn't allowed to work. So, how do I create a link to a secure page without hardcoding it to the https:// URL ?

If that page is supposed to be accessed via SSL, why don't you want to hard-code it to be an SSL link ?
What's it linking to ?

for when I switch domains and servers. For example, right now I'm using shop.mydomain.com. But I may want to switch to www.mydomain.com or someotherdomain.com. Plus, I test on my local machine and then ftp everything up to the live site... so hard coding would not work when it's on my test machine.

And just to make sure I'm stating it correctly, I don't mind hard coding it to something like https:// . some_variables . or_some_functions or something like that. But I don't want to hard code it to https://shop.mydomain.com/index.php?main_main=contact_us

You'll likely need to follow something like what swguy has mentioned here:

Thanks, that worked perfectly! And it's much easier to set up then the daunting long page of instructions that may scare one off.

For others' benefits, the way I created the define to get a secure SSL link from within a product description (after adding the prescribed, little bit of custom code to tpl_product_info_display.php):

 define('SSL_LINK_CONTACT_US', '<a href="' . HTTPS_SERVER . DIR_WS_HTTPS_CATALOG . 'index.php?main_page=contact_us">' . 'email us' . '</a>');
