What is a Factory Design Pattern in PHP?

Question

This confuses me, in the most simplest terms what does it do? Pretend you are explaining to your mother or someone almost please.

Answer 1

For the record, in easy words, a factory like @Pindatjuh said, returns a object.

So, what's the difference with a constructor? (that does the same)

1. a constructor uses his own instance.
2. Something i want to so something more advanced and i don't want to bloat the object (or add dependencies).

3. Constructor is called when each instance is created. Sometimes you don't want that.

   For example, let's say that every time i creates an object of the class Account, i read from the database a file and use it as a template.

Using constructor:

class Account {
      var $user;
      var $pwd;
      var ...
      public __construct() {
         // here i read from the file
         // and many other stuff
      }
}

Using factory:

class Account {
      var $user;
      var $pwd;
      var ...
}
class AccountFactory {
      public static Create() {
         $obj=new Account();
         // here we read the file and more stuff.
         return $obj;
      }
