Static Properties in OOP in PHP
In addition to static methods, you can also create
static properties. Such properties are also
declared using the keyword
static:
<?php
class Test
{
public static $property;
}
?>
You can write something to a static property and read from it. The property name is specified with the dollar sign:
<?php
Test::$property = 'test';
echo Test::$property; // outputs 'test'
?>
Create a Num class that will have
two public static properties: num1
and num2. Write the number
2 to the first property,
and the number 3 to the second one.
Display the sum of the property values on the screen.
