>Are you talking about C++ perhaps? ;) C++ very much applies. :) >Not using variable-variables, undeclared variables, globals, unsanitised variables in paths, SQL without prepared statements, etc. is common sense and applies to other languages too. This is a subset of what you have to avoid in PHP. Further, things like globals can have uses. That's the difference with a really poorly designed language: there are things in there that have no good use case. Not things that are only used in rare cases, things that should never be used.
