Im sending my data to PHP file like this using angularJS ajax
{ username: "someusername", password: "somepassword" }
previously i used something like this to send data
var vars = "username="+fn+"&password="+ln;
but since angular sending data like JSON. i want to decode into PHP variables.
here my PHP code
if(isset($_POST['username']) && isset($_POST['password'])){
$username = $_POST['username'];
$password = $_POST['password'];
}
$sql = "SELECT * FROM member WHERE username = '$username' AND password = '$password'";
what i tried to do is something like this
$array = json_decode(file_get_contents('php://input'))
$username = $array->username;
$password = $array->password;
$sql = "SELECT * FROM member WHERE username = '$username' AND password = '$password'";
but not sure how to do it. also no idea about what happens in this section 'file_get_contents('php://input')' im sending data from local computer to internet server PHP file (Cross Domain)
To transform a PHP array into variables use the extract function , however, this is not a good approach.
Decode the JSON into an array and use PHP's filter functions
On the client side you need something like:
$http.post(http://your.url, {"username" : someUserName, "password": somePassword} ).then(function (data, status, headers, config) { // do things. });
On the server side you should have:
$input = json_decode( file_get_contents('php://input'), true );
$username = filter_var($array['username'], FILTER_SANITIZE_STRING));
$password = filter_var($array['password'], FILTER_UNSAFE_RAW));
// this should work but is bad practice. Don't do it.
// extract($input);
// $username and $password are now available to you
Also, you need to improve you code to protect against SQL injection.

在AngularJS中使用$ http.post,然后传递带有帖子的JSON数据,然后在PHP中将$ _POST变量与json_decode一起使用,然后在PHP中将有一个关联数组。
