Php variable in script

Question

I am working on a web app. I am coming across situations where I need to access php variable in script and change its value. How can I accomplish this?

Answer 1

You simply cannot do that. You can assign php value to javascript variable, but you cannot assign javascript value to php variable. understand the server side and client side first.

Answer 2

yeah you must create an api in php

gabby is correct, directly, but by creating a form to post/get data to a php script which will give you access to the variables that you need it is possible and quite common I might add

server side -> client side is a one way street, but by creating a second script (or a function in the first) you can achieve 2 way communication

Answer 3

yes you cant change server side value from client side so simply call Ajax to set or change value
