Resolve PHP post string

Question

I have the following post string:

Name=John&Age=33&Question1=What's+your+gender%3F&Answer1=Male&Question2=What's
+your+education%3F&Answer2=Graduate

I'm going to have randomly generated amount of questions each time so I won't be able to know number of passed variables. Thus, I am searching for a solution something like:

foreach($postItem as $varr) {
    echo $varr["name"].": ".$varr["value"]."<br />";
}

Sorry for terminology. It is a serialized ajax post. Isn't called as "post string"? — Litestone, Mar 04 '15 at 18:23

Ignore what A Duff said - they probably aren't aware that GET and POST payloads look the same. — Rich Bradshaw, Mar 04 '15 at 18:23
@A.Duff post variables are delivered to the server the same way get vars are. — castis, Mar 04 '15 at 18:24

Post them as answer[1], answer[2] etc instead of answer1, answer2, and PHP will turn them into an array for you.

Hmm... Should I arrange this in `$.post`? I am using `data: $(form).serialize()` simply. Can you show me a brief example, please? – Litestone Mar 04 '15 at 18:27

You can just make the inputs have the right name, e.g. ``, then in your PHP use `print_r($_POST['answer'])` to see how that looks. – Rich Bradshaw Mar 04 '15 at 18:28
Ah, that simple. Ok then, thanks! – Litestone Mar 04 '15 at 18:30

//parse query string to an array ($output)
parse_str($postString, $output);

echo $output['Name'] . ': ' . $output['Age'] . '<br />';

//process questions
$i = 1;
while (array_key_exists('Question' . $i, $output)) {
    echo $output['Question' . $i] . ': ' . $output['Answer' . $i] . '<br />';
    $i++;
}
