The expression
$this->command of type string|false is loosely compared to false ; this is ambiguous if the string can be empty. You might want to explicitly use === false instead.
In PHP, under loose comparison (like For '' == false // true
'' == null // true
'ab' == false // false
'ab' == null // false
// It is often better to use strict comparison
'' === false // false
'' === null // false

conditions), values of different types might be equal.For
string
values, the empty string''
is a special case, in particular the following results might be unexpected:
