Initializing arrays

In most tutorials I don't see people initializing arrays. In other places I hear that it is good practice and can help PHP deal with certain scenarios. Should I be initializing all my arrays?

Yeah it is a good practice to initialize arrays

Thanks. It makes sense to me to initialize all variable as well.

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
