Return data from PHP

Hey quick question. I have a basic auth form working right now. Right now it is just sending a string "success" when login is successful and "false" when it is not. When its successful I want to return the users data like first name, last name, address etc. How can I do that?

I am using the createHTTPClient() to do the authentication through a php file right now.

I use Jquery && JSON. If the login is successful, PHP will return a JSON array with all the users info, if it isn't successful, it returns a json array [false]
```
$.ajax({type: "GET",url: 'YOURURL',data: string,timeout: 10000,success: function(res) {
yourcode
});
```

- Hey John,
  I understand that and that is already working for me. Rather than returning a string of text, I'd like to return an object array or something similar.

This should work
```
loginReq.onload = function(){
    var your_response = this.responseText;
}
```

- Gotcha…
  
  In PHP you could say something like this:
```
<?php
$response = array('loggedin' => true, 'someotherdata' => 'test');
echo json_encode($response);
?>
```
```
    var json = this.responseText;
    var response = JSON.parse(json);

    alert(response.loggedin);
    alert(response.someotherdata);
```
  This would read in the text and return a variable called response the would be an array/object assuming your PHP returned some JSON.

well what I am using is pretty easy. I dont want to bring in jquery. Does my method only return text?

loginBtn.addEventListener('click',function(e)
{
    if (username.value != '' && password.value != '')
    {
        loginReq.open("POST","http://localhost:8888/post_auth.php");
        var params = {
            username: username.value,
            password: Ti.Utils.md5HexDigest(password.value)
        };
        loginReq.send(params);
    }
    else
    {
        alert("Username/Password are required");
    }
});
