[quote author="trenchard" date="1257286355"]Thanks. It makes sense to me to initialize all variable as well.[/quote]
If nothing else you never again run into those darn PHP errors that refer to referencing an uninitialized variable. It helps for lots of reasons, and it is indeed just a good practice and habit to have. PHP is one of the only languages that even lets you get away with using variables without initializing.
One thing I do not do, however, is go out of my way to initialize everything if I'm going to be using something for the first time and immediately assigning it to a variable. For instance:
Code:
$var = $foo + 2 / 1.5;
$temp_var = $var;
$var++;
In both cases I see no reason to just initialize to be initializing - so don't get too carried away
