The non technical explanation is before is you had 100 items and it took you 100 microseconds for in_array with 10 000 items it would take you 10 000 microseconds. while with the second one it would still take you 100 microsecond if you have 100 , 10 000 or 1 000 000 ids.

(the 100 microsecond is just a number pulled out of thin air used to compare and not an actual time it may take)
