This is probably a very trivial question, but I haven't been able to find the answer neither through web search engines, nor on php.net. Please just direct me to where I can read about this, if you haven't got time to explain.
It's for declaring class member variables in PHP4, and is no longer needed. It will work in PHP5, but will raise an E_STRICT warning in PHP from version 5.0.0 up to version 5.1.2, as of when it was deprecated. Since PHP 5.3, var has been un-deprecated and is a synonym for 'public'.
Example usage:
class foo {
var $x = 'y'; // or you can use public like...
public $x = 'y'; //this is also a class member variables.
function bar() {
}
}
The var keyword is used to declare variables in a class in PHP 4:
class Foo {
var $bar;
}
With PHP 5 property and method visibility (public, protected and private) was introduced and thus var is deprecated.
In PHP7.3 still working...

If declared using var, the property will be defined as public.
here and now in 2018 using var for variable declaration is synonymous with public as in
class Sample{
var $usingVar;
public $usingPublic;
function .....
}
