php函数__construct（）涉及this-> get = $ _GET的问题

Question

I'm working on someone's code and they have a constructor that uses:

class qwerty {
public function __construct(){
// some other code
    $this->get = $_GET;
}
}

My question is this: Is it possible to sanitize the data within the constructor? Even using some simple function like strip_tags()?

Example of usage:

$qwerty = new qwerty;
qwerty->get['id'];

Answer 1

I see two ways to approach it. One would be to just use a foreach loop in the contructor to loop through the $_GET parameters

foreach($_GET AS $key => $val)
{
  $_GET[$key] = sanitize($val);
}

Alternatively, retrieve the data via a get function and sanitize there.

function getParams($key)
{
  return sanitize($_GET[$key]);
}
