Passing Variables (JS --> PHP)

Is there any way to pass variables from JS to PHP?
I thought of a couple ways myself...

1. Create a window with a url like this: http://www.site.com/JS2PHP.php?varlist=Name:JSinputname|Age:50|Exit:Yes, then use PHP to split the "|" then split the ":" and then after 1 second, automatically close the popup since the variables are passed... then what? Can you do this with PHP 5?

PHP Code:

---

<?PHP
    // JS2PHP.php
    $VarList = $_GET["varlist"];
?>

---

Will that variable be accesible from this?

PHP Code:

---

<?PHP
    // EchoVar.php
    echo $VarList;
?>

---

2. using this

HTML Code:

---

<SCRIPT>
    var JSVAR = nameinput.value;
    document.write("<?PHP $JS_Var = \"" + JSVAR + "\"; ?>");
</SCRIPT>

There are only two ways to pass a JavaScript variable to PHP. You can implement these with AJAX or by loading a new page.
1. Using $_GET.
2. Using $_POST.

Note: Your second option will not work because the server-side code (php) would already have been executed before the JavaScript (client-side) could write it using document.write. Since PHP is server-side it cannot be written dynamically like JavaScript.

Additional to PeejAvery answer here are two small examples

Ok thanks...but can you access $num1 in script1.php from script2.php?
Do you have to make it global?

In order to access PHP variables between PHP scripts you can do a number of things.

1. Work with sessions and make it a session variable.
2. Store it in a cookie.
3. Use include(), include_once(), require(), or require_once().
