global.this

Code example

<?php declare(strict_types = 1);

function foo(): void {
	global $this;
}

Why is it reported?

PHP does not allow $this to be used as a global variable. The $this pseudo-variable is reserved for referring to the current object instance inside class methods, and it cannot be imported from the global scope with the global statement. This is a compile-time error in PHP.

How to fix it

Use a different variable name:

 function foo(): void {
-	global $this;
+	global $instance;
 }
