url parameter of ajax for specific function

i want to set url parameter of ajax to a function of class and return the value of that function but my problem it seems cant access to function and nothing returns

this is my script:

$('#send').click(function (e) { //event added
    e.preventDefault(); //prevent normal for submit
    $.ajax({
        type:'post',
        url:'localhost/shapeproject/controllers/Square/getArea',
        data:{'edge':edge},
        success:(function (response) {
            alert(response);
        })
    });
});

this is my class:

<?php
class Square extends Shape
{
    private $edge;

    function __construct()
    {
        $this->edge = $_POST['edge'];
    }

    public function getArea()
    {
        return $this->edge * $this->edge;
    }

    public function getPerimeter()
    {
        return $this->edge * 4;
    }
}

you can add a page and name it ajax_handle.php. then link to that page in your ajax code like this

$('#send').click(function (e) { //event added
    e.preventDefault(); //prevent normal for submit
    $.ajax({
        type:'post',
        url:'ajax_handle.php',
        data:{'edge':edge, getArea: true},
        success:(function (response) {
            alert(response);
        })
    });
});

now in your ajax_handle.php you can write this code.

if(isset($_POST['getArea']) && $_POST['getArea'] == true)
{
    $obj = new Square();
    $obj->getArea();
}

You must have a front controller to manage this process.

For example: create a file called index.php inside shapeproject directory.

Then you can extract controller and function names from $_SERVER['REQUEST_URI'].

You may need to use some .htaccess directives like the example below:

RewriteEngine on RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule ^(.*)$ /index.php

but you don't set any data... Add data to the jquery function;

$.ajax({
    type:'post',
    url:'localhost/shapeproject/controllers/Square/getArea',
    data: { edge: 'xyz' },
    success:(function (response) {
        alert(response);
    })
});
