I need to assign javascript client Date (examp. - 2012/02/03 16:00:00) to php variable. Any idea how? I was trying to use this lines and changing them in million different ways. But I just cant get it.

Today = new Date();
var date = ????
var date = "<?= $date ?>";

I solved it this way:

<input id="date" type="hidden" name="date">
<script type="text/javascript">
     document.getElementById('date').value = Date();
</script>

But thank you very much all.

You want the client date in your php code? Not possible in the way you are doing it. Pay attention at how the client-server model works, you can't mix client logic and server logic that way. – gpasci Mar 3 at 19:37
Yes, now when I think about it's true. But if I wanted javascript date variable put into form, into hidden input how would I do that? – Jakub Zak Mar 3 at 19:40
You can implement an ajax solution to make a call to your php script to pass the current client time to your server. – gpasci Mar 3 at 19:42
But if this form with hidden input is not in php but in html do I still need to use ajax? – Jakub Zak Mar 3 at 19:44

Add an input in your form

<input type="hidden" name="clientDate">

if you are using jquery add this to set the client date input when the user submits the form

$(YOUR_FORM_SELECTOR).on("submit", function() {
  $("[name=clientDate]").val(new Date());
});

If you want to go with vanilla javascript follow this answer

To be honest I never used jQuery so I do not really know how? I just now am thinking about getting client side date(). Assigned it to html form to hidden input. Pass it by post to another page where php will take it as $_POST["#"]. – Jakub Zak Mar 3 at 19:54
follow the link in my answer...hope it helps – gpasci Mar 3 at 19:58
I found about 5min ago same one. :) thank you very much – Jakub Zak Mar 3 at 20:01
What would be an example form selector? Say I had a form like... <form name="signup" id="signup1" method="post"> – Amyunimus Mar 23 at 21:52
$("#signup1"); api.jquery.com/category/selectors – gpasci Mar 23 at 23:40

you can't simply assign a javascript variable to a php variable. php runs on the serverside and is executed before javascript.
you can however submit an ajax call with the value of your javascript variable to a php script.
you might wanna have a look at jquery's post function.

$.post("test.php", { yourDate: date } );

in your PHP script you'll be able to access the date with $_POST['yourDate'] you can also use a form and a hidden field as you say in your comment.
in this case you can use (assuming you're using jQuery)

$('#id_of_input').val(date);

ok I'm gonna ask different way than. I have a form, I have a hidden input to which I would like to assign javascript variable. Is that possible? Concretely time. – Jakub Zak Mar 3 at 19:37

You can not assign it directly. You ca do this only by creating a http request. In this case using ajax

Yes, it works, I used it in a website I made. It's not perfect but it's nice to use! – Frederick Marcoux Mar 3 at 19:37

@FrederickMarcoux no it doesn't. what you're doing is assigning a PHP variable to js. Jakub asked for the opposite – stratton Mar 3 at 19:39
@FrederickMarcoux You can not assign a JS variable to PHP assuming JS is running under a web browser. – shiplu.mokadd.im Mar 3 at 19:44
Okok, I didn't understood the question correctly... – Frederick Marcoux Mar 3 at 19:52
