1.2.1124. Simple Global Variable¶
The global keyword should only be used with simple variables. Since PHP 7, it cannot be used with complex or dynamic structures.
<?php
// Forbidden in PHP 7
global $normalGlobal;
// Forbidden in PHP 7
global $$variable->global ;
// Tolerated in PHP 7
global $\{$variable->global\};
?>

1.2.1124.1. Suggestions¶
Add curly braces so the syntax is compatibles PHP 5 and PHP 7
Remove this syntax, and access the variable through another way : argument, array, property.
