Question about _clone

HI

what is the advantage of using _clone in a class and what does it do?

Could you give a example of usage of that.

And in What situations we should use that?

 

tnx

Clone does exactly what the name says. It takes an object and creates the exact copy of it. When dealing with objects you have to keep in mind all variable passing is done by reference.

 

$objOne = new StdClass();
$objOne->name = "Object One";

$objTwo = $objOne;
$objTwo->name = "Object Two";

 

Now the name property of both variables is "Object Two". This won't happen if you use clone method. Note when some of the objects properties are also objects you need to clone these as well to get fresh new ones.
