Doesn't this pose a potential problem? What if we need the array keys to be [101], [102], [103] etc.?
For example they keys were to indicate an isbn? What is the best way to handle this?

23,932 PointsThanks for taking the time Luc, but this wasn't what I was asking. I understand how arrays work. I am referring in this lesson to when we pull the information from a database. The database converts the info into an array, but reassigns they array keys to [0],[1,],[2] etc. But earlier in the lesson we were using our own custom defined keys such as [101], [102], [103] etc. What happens to these custom defined keys?
