Only declaring a single property per statement allows you to later on add doc comments more easily.
It is also recommended by PSR2, so it is a common style that many people expect.
$limit
The PSR-2 coding standard requires that all properties in a class have their visibility explicitly declared. If you declare a property using
class A { var $property; }
the property is implicitly global.
To learn more about the PSR-2, please see the PHP-FIG site on the PSR-2.
