1.2.1289. Unused Global¶
A global keyword is used in a method, yet the variable is not actually used. This makes PHP import values for nothing, or may create interference
<?php
function foo() {
global bar;
return 1;
}
?>
1.2.1289.1. Suggestions¶
Remove the global declaration
Remove the global variable altogether
