Variable declaration in PHP

Question

PHP

Answer received , thanks to everyone ... for the minuses in karma - especially :-\

I googled for a long time, but I didn’t find a clear answer - classes, OOP, etc. are everywhere :( I ask you, gentlemen:

What is the fundamental difference between:

function f() {
var $variable = 1;
... }

and
function f() {
$variable = 1;
... }

Answer 1

var does not exist in nature, it is from php4, it is not in the fifth. You should always use $foo = 'bar';

Answer 2

PHP is not JS. "var" is the old way of declaring class fields (now private, protected, public). And, by the way, it googles .

Answer 3

The first option is only suitable for classes
class bbb {
var $i=1;
}
although it is deprecated. This will not work in a
function function bbb() {
var $i=1;
}
will just give an error
. And the second option is only good for functions and "just code" if you define
class bbb {
var $i=1;
}
then it will throw an error.

Answer 4

That the first option is Parse error?
PHP5.3 at least.

Answer 5

I asked ... without classes! :(
