It seems like $parts can also be of type false; however, parameter $var of count() does only seem to accept Countable|array, maybe add an additional type check?
                                                                                                                                                                                           (

 If this is a false-positive, you can also ignore this issue in your code via the ignore-type   annotation

It seems like you are calling the size function count() as part of the test condition. You might want to compute the size beforehand, and not on each iteration.
                                                                                                

                    
                                            

                            

                            

                                
                                    
                                
                            


                            
If the size of the collection does not change during the iteration, it is
generally a good practice to compute it beforehand, and not on each iteration:


for ($i=0; $i<count($array); $i++) { // calls count() on each iteration
}

// Better
for ($i=0, $c=count($array); $i<$c; $i++) { // calls count() just once
}
