How to get the value after the hash in “somepage.php#name”?
Is it possible to get an anchor name with PHP?
For example, for this URL:
http://domain.com/#departments
How can I get the text "departments"?
There is no way to get things after "#" in php, because this data is not provided to server, only url without data after "#", but if you are executing php script through JavaScript, you can Always split url into "#" and send the data as parameter or value of some hidden field.
