Cannot access static:: when no class scope is active

Description

static refers to the class that was called to access the class elements (constants, method, properties..). As such, static can only be used inside a class or a trait.

Example

<?php

static::x;

?>

Solutions

• Move the code inside a method, in a trait or a class.

• Use the full name of the class that should be used.

In more recent PHP versions, this error message is now Cannot use “static” when no class scope is active.
