Proper way to declare multiple vars in PHP

Question

I\'ve been coding personal scripts for years in PHP and get used to turn off Error display. I\'m about to release some of these scripts and would like to do it the proper way.

Answer 1

Why not just set them?

If you're trying to preserve the value in them, then yes that's the correct way in general. Note that you don't need the second pair of brackets in your statements:

if (!isset($foo)) $foo = '';

is enough.
