How can one call a PHP function from JavaScript?

Question

I have a piece of code, and I need to call a PHP code snippet when this function is called. Basically, it would be like this:

function jsFunc(){
    //do PHP stuff
}

I don't know if this is a trivial thing, and I'm just not getting it, but I would appreciate any help.

you would need to expose this function via the PHP Api can call the endpoint from Javascript via $http.get or something similar — Jarek Kulikowski, Jul 20 '17 at 17:20

Do the following:

function jsFunc(){
    var php_code = <?php 
    // your php code
    ?>;
}

EDIT: To call an object within the php code, use

echo $php_object

as suggested by noobcode.

If you want to do that in a .js file you can organize with Ajax calls

or if you use jQuery library

Run it like:-

function jsFunc(){
//do PHP stuff
  $pp = <?php echo "hello"; ?>;
  console.log($pp);
}

Now you can easily use your function where i have used echo.

This solution "works" for static data like echoing a fixed string. You have to consider that the PHP bit is only evaluated once before it is sent to the client. On the website would look like this: $pp = "hello"; This does not really help if you want to fetch more dynamic data. For that see the other answers about AJAX on the main question. – B.Friedrichs Jul 20 '17 at 17:25
yes. for that you need to use ajax. – Harpreet Singh Jul 20 '17 at 17:27
