Depending on which generation/incarnation of PHP you mean, you're
correct. Forms Interpreter (PHP/FI and PHP/FI 2.0) had variable
scope, but the original - the very Granddaddy, Personal HomePage Tools
- did not, if memory serves. That initial implementation was actually
nothing more than a small series of Perl scripts. When Rasmus rewrote
everything in C, that's when variable scoping was introduced (again,
fairly certain).
