What if $host were "1"? The important part to note about this is that a
string, when evaluated in a numeric context, has to be turned into a number.
If the first character of the string is not a number, then the string
evaluates to 0; if, on the other hand, the string starts with numbers then
those numbers are used. For example, "400abcde" evaluates to 400 in numeric
context.
So, if $host were "1", then $host == 'access_2' would be false.
