Anyone who has worked with PHP knows that it is extremely permissive with variables and their types. There's no need to declare variables, not even at class level, and data types cannot really be enforced. This is one of the greatest strengths of weakly typed dynamic languages, but it can be easily used the wrong way.

The solution is to put as much code as possible into different specific functions/methods so this wont be a problem.

Never say, "this is better than that". In code it's all about context, in some cases reusing vars can be clean and easy to follow. And in some cases it's not. In the example, it makes total sense not to reuse the fruit var, but thats just one case. Generalizing is never a good thing.

Funny :)
I can give simpler example, never do:
$i=1;
...
$i=2;
How knows... May be you'll want to use old value of $i :)
