wildteen88 Posted June 22, 2006 Share Posted June 22, 2006 They are both the same! 4.3 just has bug fixes and secuirty updates that it.Obviously the advantage between the two is go for the latest one as it has the bug fixes and the security holes fixes.

zq29 Posted June 22, 2006 Share Posted June 22, 2006 Books that teach PHP4 often cover alot of the features of PHP 4.x.x, PHP4 is just a generalisation as "sub-versions" get released on a some-what regular basis.Although, there were a handful of new functions that were implemented in PHP 4.2.x, there would be no fundimental differences in the syntax or functionality of the language.

wildteen88 Posted June 22, 2006 Share Posted June 22, 2006 Because prior to PHP 4.3.x a setting called register_globals was turned off by defualt, however the tutorials/books you are reading either old or haven't been updated yet. You can tell when a book has been updated as it'll have something like: [i] edition x[/i] some where on the cover. x being the number of times books have been rewritten.But most tutorials was done before PHP 4.3.x was released, however still people tunr this setting register_globals on despite this setting can cause secuirity holes within a script.
