You have to remember that if JS and PHP live in the same document, the PHP will be executed first [at the server] and the JS will be executed second [at the browser]--and the two will NEVER interact [excepting where you output JS with PHP, which is not really an interaction between the two engines].
With that in mind, the closest you could come is to use a PHP variable in your JS:
var a = ''; //outputting string foo in context of JS
//must wrap in quotes so that it is still string foo when JS does execute
//when this DOES execute in the browser, PHP will have already completed all processing and exited
To do that, you can simply use echo[] function into Javascript variable value. If the PHP data is array or object, first you need to convert it to Json object using json_encode[] function. Then you can easily manage Json object in Javascript. This way, you can pass data from server-side to client-side and manage.
Simply placing the PHP code inside JavaScript will not work in this case either. The reason you can’t simply call a PHP function from JavaScript has to do with the order in which these languages are run. PHP is a server-side language, and JavaScript is primarily a client-side language.
