How do I add a hyperlink to a mail form?

I have a PHP mail form with the following as an input to the body of the message:

$message =
“Name: " . $_POST[“name”] .”
".
“Company: " . $_POST[“company”] .”
".
“Phone: " . $_POST[“phone”] .”
".
“Email: " . $_POST[“email”] .”
".
“Job Description: " . $_POST[“jobdescription”] .”
".
“PO#: " . $_POST[“po”] .”
".
“Comments: " . $_POST[“comments”] .”
";

I want to add a hyperlink to the code but I’m not quite sure of the syntax. Something to this effect:

<a href=“www.mysitelocation.com”>Get Files</a>
