You should think of the page as being built into one contiguous page, so that if you include a number of .asp files they will build up your finished page. For instance, if you have three files: File_1.asp <h1>Hello, World!</h1> File_2.asp <p>This file will be included too!</p> File_3.asp <%Dim version version = 1.1%> …and include … Read more
You get to the size of elements, which is 1. However, if your array has only one element, which is the case for 1-digit numbers, then sizeof($_array) === 1.
