Application of SSI in PHP program

1. What is SSI?

Server-side embedding: Server Side Include, an ASP-based Web page authoring technology. Before you send content to your browser, you can use the server-side include (SSI) directive to include text, graphics, or application information in a Web page. For example, you can use SSI to include a time/date stamp, a copyright notice, or a form for customers to fill out and return. For text or graphics that appear repeatedly in multiple files, it is an easy way to use include files. Save the content in one of the included files without having to enter the content into all the files. The include file is called with a very simple statement that instructs the WEB server to insert the content into the appropriate Web page. Also, when you use the Include file, all changes to the content can be done in one place only.

[2] Insert text content directly into the document < #include >
