RE: [PHP] Variable name declarations?

It would nice to introduce more runtime checking of array types and complaints in case non-array values are used in functions. But otherwise the strong type checking will just cause more problems and more overhead with calls. I don't know if the example above will help that much, but you could already write similar code in functions to make sure that the values are declared on top, to make things clearer. --Kent
