Answer 1

You must not use var to declare a variable : just assign a value to it, when you need it :

$your_variable = 5647;

And if you really want your variables listed beforehand, just assign something that would mean no-value to them, like, for instance, null :

$your_variable = null;

Just so you know : var was used, in PHP 4 (and, as such, is still valid in PHP 5, for that same usage) to declare classes properties.
