Hmmm, I don't think other programmer's sloppy coding practices are a good argument for having to declare variables or against loose typing. There are crappy coders in whatever language you use. The good coders will do the right thing. If you are concerned about scripts on hotscripts.com where the coder doesn't seem to understand the principles of security or fully understand what is happening with their variables, then perhaps you should be writing the code yourself or hiring someone who does understand the language more completely. Caveat Emptor. Part of PHPs simplicity and attractiveness is that you DON'T need to declare variables, and you DON'T need to do manual casting. Start adding these and you may as well be writing Java or C/C++.
