Hi Rob, >From my reading of PHP documentation: PHP does define classes explicitly, if that is what you mean by data structures. Once declared, also, these classes become types. PHP does not have any private variables, does have coding conventions that say you should not try to address variables beginning with a single underscore. As for other data structures--PHP use a hash fo for its array type. If you It can be used as either array or hash. Since the key is required to be unique, numerical indexing will work. You could just as easily declare a string as the index, though. Neither language is strongly typed, as C, Java, or VB are. Although both are type-sensitive, they still restrict identifiers only by contaiment class. I'd suggest that you look at Jenda's advice also. Take Perl for what it is. It works. Once you get over the difference in paradigm from C-type languages, you will find that P-OOP has it's own internal logic.
