If it could be a string or an integer key - as you mentioned, then you wouldn't use that option, right?

That works fine in most situations, but not always - such as searching for a value in an array created by array_keys when the value you are searching with is a string, but may also be a valid integer. In the array it will be stored as an int and will fail on the search. (That is the issue I ran into at work.) The other place that strict does not work is in switch statements, where you don't have that option.
