Local variable assign versus direct assign; properties and memory
Category : Programming Languages

In objective-c I see a lot of sample code where the author assigns a local variable, assigns it to a property, then releases the local variable. Is there a practical reason for doing this?

PHP assign value to $this
Category : Development Tools & Services

Basically what I'm trying to achieve is to make the object reference another object of the same class - from inside of a method. It'd be perfect if the following would work:

$this = new self;

But one cannot reassign $this in php.
