How to capture a Javascript function's return value into a PHP variable?
Example:
Javascript: javascriptFunction { return null;};
PHP: $php_variable = javascriptFunction();
If clarification is needed, please let me know.

JavaScript runs on the client side, while PHP runs on the server side. As such, you cannot execute JavaScript code inside your PHP code; however, these two components can communicate via several channels including:
The easiest approach would be to set a query parameter on your URL: example.com/?variable=value and access it from your PHP script using, $_GET['variable'].
Hope this helps.

Without any idea of what you're trying to do...
Use jquery (with ajax):
$.get("test.php", { name: "John", time: "2pm" } );
Where test is the php file you're sending data to, and John and 2pm are the data.
Then in test.php do:
$name = $_GET['name']
and do the same for time!

You would have to AJAX the value to the server and pull it from $_GET or $_POST:
$.ajax({type:"get", data:javascriptFunction(), url:script.php });
Then, simply use $value = $_GET.
