I created this library, may be of help to you. MyPHP client and server side library

Example:

<!DOCTYPE html>
<html>
<head>
    <meta charset="utf-8">
    <meta http-equiv="X-UA-Compatible" content="IE=edge">
    <title>Page Title</title>
    <meta name="viewport" content="width=device-width, initial-scale=1">
</head>
<body>

    <!-- include MyPHP.js -->
    <script src="MyPHP.js"></script>

    <!-- use MyPHP class -->
    <script>
        const php = new MyPHP;
        php.auth = 'hashed-key';

        // call a php class
        const phpClass = php.fromClass('Authentication' or 'Moorexa\\Authentication', <pass aguments for constructor here>);

        // call a method in that class
        phpClass.method('login', <arguments>);

        // you can keep chaining here...

        // finally let's call this class
        php.call(phpClass).then((response)=>{
            // returns a promise.
        });

        // calling a function is quite simple also
        php.call('say_hello', <arguments>).then((response)=>{
            // returns a promise
        });

        // if your response has a script tag and you need to update your dom call just call
        php.html(response);

    </script>
</body>
</html>

use document.write for example,

<script>
  document.write(' <?php add(1,2); ?> ');
  document.write(' <?php milt(1,2); ?> ');
  document.write(' <?php divide(1,2); ?> ');
</script>

If you actually want to send data to a php script for example you can do this:

The php:

<?php
$a = $_REQUEST['a'];
$b = $_REQUEST['b']; //totally sanitized

echo $a + $b;
?>

Js (using jquery):

$.post("/path/to/above.php", {a: something, b: something}, function(data){                                          
  $('#somediv').html(data);
});

You need to create an API : Your js functions execute AJAX requests on your web service
```
  var mult = function(arg1, arg2)
    $.ajax({
      url: "webservice.php?action=mult&arg1="+arg1+"&arg2="+arg2
    }).done(function(data) {
      console.log(data);
    });
  }
```
on the php side, you'll have to check the action parameter in order to execute the propre function (basically a switch statement on the $_GET["action"] variable)

Try This

<script>
  var phpadd= <?php echo add(1,2);?> //call the php add function
  var phpmult= <?php echo mult(1,2);?> //call the php mult function
  var phpdivide= <?php echo divide(1,2);?> //call the php divide function
</script>
