The expression $parent of type false|string 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 ==, or !=, or switch 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:


''   == false // true
''   == null  // true
'ab' == false // false
'ab' == null  // false

// It is often better to use strict comparison
'' === false // false
'' === null  // false
