Accessing Static Through Class and Object in OOP in PHP

Static properties and methods can be accessed both through the class, and through a variable with an object of the class.

Let's look at an example. Let's say we have a class Test with a static property:

Test.php<?php
  class Test
  {
    public static $property = 'static';
  }
?>

Let's output the value of the static property, by accessing the class:

index.php<?php
  echo Test::$property;
?>

And now the value of the static property, by accessing the object of the class:

index.php<?php
  $test = new Test;
  echo $test::$property;
?>

Test.php<?php
  class Test
  {
    public static function show()
    {
      return '+++';
    }
  }
?>
