PHP Operational Trail

In this lesson we will tackle about the operation of the server to process PHP code. I will show the diagram first then I’l explain after. This has actually happened when you ask for the URL (Uniform Resource Locator) in your browser before you get back your HTML return back to you. So we have our browser and the web server and its called apache. And our “web browser” will make a request to “Look for a Page” and the page is located on the hard drive something we call “Sample.php” and since it has a “.php” extension it tells the web server to “process php” files and for those PHP tags located in there, and this process by the server. If the process file contains operation on the database, then it ask and receive data from the database. And finally the server will then returns pure HTML code to the browser which browser can easily understand. And as long this concept is in your mind php will lot more in your sense. I hope this tutorial would help to understand the php Operational Trail Concepts.
