Where should mysqli object be created?

Question

PHP

Всем привет! Пишу сейчас обращение к БД через ajax.
     $.ajax
     ({
       url:  "server.php",
       data: {   func:"RegUser", password:$("#reg_password").val(),email:$("#reg_email").val() },
       success: function( data )
       {
  		//  ответ
       }
});

Server:
if ( $_GET["func"] == "RegUser" )
{
}

Now the question is: Where should I include mysqli object creation? In the Get request or outside of it globally? And will the object be saved the next time it is accessed. What's the best way to do it?

Answer 1

Each ajax request, as well as the opening of each page, re-runs the php script on the server.
Therefore, from the point of view of saving the object between ajax requests, there is no difference - the object will always be created anew.
