PHP从角度http请求中获取INT

Question

How to get an int-value from an $http-request in PHP ?

I´m trying to send a http request from an Angular app but i´m not able to get the value of the sent `id`` parameter into my PHP variable $id.

I tried several methods like:

$id = $_POST['id'];

or

$id = $connection->real_escape_string(isset($_POST['id']) ? $_POST['id'] :'');

in my PHP but nothing works...

This is my function to send the $http request

function removeFriend( id ) {
        var request = $http({
            method: "delete",
            url: "php/deleteFriend.php",data: $.param({'id':id}),
            headers: {'Content-Type': 'application/x-www-form-urlencoded'}
        });
        return( request.then( handleSuccess, handleError ) );
    }

The problem was the method of the $http request. you have to use POST so PHP can get the values with the $_POST['id'] method.

So here is the code that works:

Javascript

function removeFriend( id ) {
        var request = $http({
            method: "post",
            url: "php/deleteFriend.php",data: $.param({'id':id}),
            headers: {'Content-Type': 'application/x-www-form-urlencoded'}
        });
        return( request.then( handleSuccess, handleError ) );
    }

PHP

$id = $_POST['id'];
