Question

Do I need to escape my object data if I’m serializing for mysql injection?

ie:

class Object
{
   public $description;
}

$obj = new Object();
$obj->description = mysql_real_escape_string("this is my crazy string with lot's of bad // characters");

$data = serialize($obj); // <-- $data will be stored in DB

or will this suffice:

class Object
{
   public $description;
}

$obj = new Object();
$obj->description = "this is my crazy string with lot's of bad // characters";

$data = serialize($obj);

Run mysql_real_escape_string() after you’ve serialized. That’s the string you are going to put in the database after all.
