Strict mode in PHP

Other languages with automatic variable declaration - like Perl - have a strict mode.

By activating this strict mode, variable declaration is required, and Perl throws an error as soon as you try to use an undeclared variable.

Does PHP offer a similar feature?

PHP is warning about undeclared variables by default; you just need to turn the error reporting level up so you'll see the notices. Note though that since there's no special syntax to declare a variable in PHP and you simply declare one by assigning to it, it can only warn you when you try to use the value of an undeclared variable. Contrary to other languages, "assignments to undeclared variables" do not exist, so PHP can't warn you there.
