53.  Do I need to know any programming to make updates?
To initially setup a site and customize it you will, though you don’t need to worry about that because that is what we are doing for you. Once the site is setup we will train you on how to perform the updates (very simple) and you will be good to go. In order to perform the content updates you may need in the future you will not need to know any programming at all. I compared it earlier to using Microsoft Word and it really is that easy!
Forget about having to hire a programmer to make simple text updates on your site from now on, you can go in and do it yourself in a matter of minutes.

54. Can you tell that whether the comparison of string “50 and integer 60 will work in PHP or not?
Yes it will work as the PHP will consider the comparators as Integer type and hence will compare 50 and 60.

55.  Will I have the ability to update my own content?
That depends on the site/project itself. We have created sites where almost every aspect could be edited by the client (content, navigation, photos, forms, etc) and others where it was a simple setup to allow for the main content areas to be edited. This is something we will discuss when planning the project and determine what your need will be. At the very least you will be able to edit the site content yourself and the ability to add/remove photos.

56. Briefly explain how include and require are different from each other?
Both include and require scans the program. If the require() function doesn’t find any file than the script will not execute. On the other hand if the include() file can’t find a file or encounter any error then the warning notification will be raised but the script will still execute.
