你能把PHP文本变成一个变量吗？

Question

I was wondering if it was possible to dynamically create variables like so:

$sender = $email = $number = $message = "";

foreach ($_POST as $key => $value) {
    if isset & !empty //loosely typed
    $+key = $value // can something like this be done?
}

if so how?

PHP does have variable variables, but you don't need that here. I think a simple associative array or object will work just fine for you.

$data = array(
  'sender' => 'Someone',
  'email' => '[e-mail]',
  'number' => 12345,
  'message' => 'some message'
);

echo $data['sender']; // Someone
