    This question is very broad. Please go do some more research and familiarize yourself with the basics of the techniques used. One of your keywords is `JSONP`. – CBroe Feb 24 '14 at 20:37

The above answer is partially incorrect; PHP doesn't have access to localStorage. However, you can use cookies to achieve what you want - although you CAN use JSON with AJAX, but I think cookies are easier. Since you're very new to JavaScript, I'll show you an example.

Let's assume I'm making a very insecure login system. Let's say:

$name = "John"; //set the name to John.

Now, to let JavaScript access this name variable, we'd have to use cookies. You can use them like so:

$username = "John"; //set the name to John.
setcookie("username", $username, time()+86400);

The setcookie method take the paramaters:

setcookie(name, value, expire, path, domain);

So in our case, it sets the name to username, the value to the user's name, the expiry date from 1 hour from now (60*60*24). This cookie will expire in one day.

Now, once this is done, make sure this function is added in your scripts.

function getCookie(name) {
  var value = "; " + document.cookie;
  var parts = value.split("; " + name + "=");
  if (parts.length == 2) return parts.pop().split(";").shift();
}

Please credit the original author at this topic for the code above.

Then, to get the cookie, simply do:

name = getCookie(username);

I hope I helped!

  • Ok, I understand all of the php. However I do not understand where I am supposed to put the url location of the php file. Sorry I must seem rather stupid asking this question. – checked01 Feb 24 '14 at 21:12
  • Just a wording issue: note that the other answer may appear above or below your answer, depending on their relative score. – halfer Feb 24 '14 at 21:32
  • @checked01, if you want it to be asynchronous, you'll have to use AJAX. I'm not that familiar with it, so you'll have to Google it :) – Riftes Feb 25 '14 at 16:56

I think you can use "cookies" or "localStorage"
