Excel VBA: Dynamic Variable Name

Note: I am limited to PHP <-> VBA. Please do not suggest anything that requires an Excel Addon, or any other language/method.

I have a function that connect to a specified URL, submits data, and then retrieves other data. This works great. I'm trying to write it so i can use it as a generic function I can use to connect to any file I need to connect to - each would return different data (one could be user data, one could be complex calculations etc).

When it retrieves the data from PHP, is there a way to dynamically set the variables based on what is received - even if i do not know what has been received.

I can make PHP return to VBA the string in any format, so I'm using the below as an example:

String that is received in vba:

myValue1=Dave&someOtherValue=Hockey&HockeyDate=Yesterday

If i were to parse this in PHP, I could do something similar to (not accurate, just written for example purposes);

$myData = "myValue1=Dave&someOtherValue=Hockey&HockeyDate=Yesterday"
$myArr = explode("&",$myData)
foreach($myArr as $key => $value){
    ${$key} = $value;
}
echo $someOtherValue; //Would output to the screen 'Hockey';

I would like to do something similar in VBA. The string I am receiving is from a PHP file, so I can format it any way (json etc etc), I just essentially want to be able to define the VARIABLES when outputting the string from PHP. Is this possible in VBA?.

The current state of the function I have that is working great for connections is as below:-

Function kick_connect(url As String, formdata)

'On Error GoTo connectError
Dim http
Set http = CreateObject("MSXML2.XMLHTTP")
http.Open "POST", url, False
http.setRequestHeader "Content-Type", "application/x-www-form-urlencoded"

http.send (formdata)
kick_connect = http.responseText
Exit Function

connectError:
kick_connect = False

End Function

Ultimately, I want to be able to do something like

sub mySub
    myData = "getId=" & Range("A1").Value
    myValue = kick_connect("http://path-to-my-php-file.php",myData)
    if myValue = False then
        'Handle connection error here
        exit sub
    end if

    'do something snazzy here to split "myValue" string (eg "myValue1=Dave&someOtherValue=Hockey&HockeyDate=Yesterday") into own variables

    msgbox(myValue1) 'Should output "Dave"


end sub

Obviously I could put the values into an array, and reference that, however I specifically want to know if this exact thing is possible, to allow for flexibility with the scripts that already exist.

I hope this makes sense, and am really grateful for any replies i get.

Thank you.
