I have a function, which is a safer way to extract variables than extract(). Basically you just specify which variable names are to be pulled out of an array. The problem is, how do you insert those variables into the "current symbol table" like extract() does? (ie. the local variable scope within a function). I can only do this by m...

I know that PHP4 is "dead", however there are about two dozen or so of our clients that still are located on servers where PHP4 is used, and we won't get any server upgrades until around a year or two. I'm just about to start working on refactoring and improving our core web framework, which is now coded for the lowest common denominato...
