Expiration date
I wanted to have an expiration date on one webpage which I made with Adobe Muse. I could use PHP or Javascript to achieve this. I can also have the expiration date in mysql as well.
My question is how to setup an expiration date for my webpage, so it does not show after the expiration date. Also, next question is how can I have this hiden, so the user can't check the view source and see the expiration date at all.

This solution is only available to members.

Whatever you do, as long as the date is NOT coded in the HTML, it will not be visible to the user. Put it in the php directly (as Angha110 shows), or in a database where you retrieve it with php, either would work.
It won't work in an HTML page, it needs to be a .php page so the php can be processed.
You have to name the page "myPage.php" so the PHP interpreter will be run. You can also something similar in javascript. Like this.

Dave - They don't want the date to be viewable
Then load it from an external file. If it's "expired" and you get rid of the alert, no one will see it when it redirects. And only developer will think to look in the external file.
Of course, they could just actually delete the file...

You can use PHP on an HTML page (one with the .html suffix) if you parse the .html files through PHP. I do this with this line in my .htaccess file
AddType application/x-httpd-php5 .html .htm .php
If you use something like this, you can choose a solution like the one here:

If you don't care that the user sees a 404 or similar, just use php and this:
<?php
if (time() <= strtotime("07/01/2014 12:00AM"))
{
?>
Put your whole HTML code here
<?
}
That will simply show a white page after the expiration date.
<?php
if (time() <= strtotime("07/01/2014 12:00AM"))
{
?>

}

Or even this:
<?php
if (time() <= strtotime("07/01/2014 12:00AM"))
{
?>
Put your whole HTML code here
<?
}
else
{
echo "This page intentionally left blank.";
}
<?php
if (time() <= strtotime("07/01/2014 12:00AM"))
{

<?
}
else
{
echo "This page intentionally left blank.";
}
As I think about this a little bit, it sounds like a "loaded question" with a subtext we may not understand. Can you please step back from the technical details a little bit and just describe why you want to do this? Why do you want the pages to expire? Why do you want to keep the expiration date a secret? If we understand the business reasons for this, we may be able to offer a more mainstream solution.

The only difference is that in mine, the result after the expiration date is a blank page, or a message, rather than a redirect to an error page.

I changed the html to php and it worked fine. (Thank you Cathal).
The reason I want this is to have an expiration date when I make demo pages for my clients. I want it to expire after certain date.
Also it would be nice to prevent them to copy the code from the demo which I believe need another ticket and conversation.
I think the php works fine, but maybe having the expiration in the database be another option.
What would you advice in these case?

It is not possible to prevent someone from copying HTML and images from a web page. Every web browser that they would use to view it allows you to Save the page and images to their computer.
For that scenario you are just adding an unnecessary step by using a database to hold a date for a single page. It would be easier to just hardcode a set date as and when you create the pages.
There would be nothing stopping them copying the HTML and there is nothing you can do about that
