Structures are everywhere in the ColdFusion world. As of ColdFusion 4.5, form, application, session, server, request, and URL variables are stored in structures. Allaire Spectra makes extensive use of structures and associative arrays. But what are they and why should you care? We all start out learning ColdFusion by outputing variables using CFOUTPUT and some pound signs. A variable with an name like myvariable was passed to the page by a form or a link and output as myvariable. By not understanding and using scope, we unwittingly add inefficiencies to our code and overlook a lot of advantages that come with using scopes. There are many things to consider when determining how you will host your ColdFusion site. Issues include tag availability, database needs, disk space, bandwidth, security, support, e-commerce, and software costs. |
