About https for sign In

Dear all,

I want something like the following.

Look at www.vworker.com

At top right side: If I click sign in it goes to a page which is https.

How can I do this using PHP?


How can I implement SSL when user click sign In (I have used relative address for example signin.php)?

It can.

If I use SSL then will it go through https?

You don’t. HTTPS requires server configurations and money.
You need to implement SSL, have a dedicated IP address, and have an SSL certificate.
Nothing to do with PHP.

If SSL already setup in server how can I implement this in script PHP?

You don’t. PHP doesn’t need to do anything.
