What Vikas said is absolutely Correct. In Joomla there is no need to write the code for
database connectivityIf we hosted the site local into web, we have to change the configuration.php
fileIn that we have to mention the database username and password details.

There is one way I know and that is mod-rewrite to hide the extensions so if I go to domain.com/apage.html mod_rewrite will change (internally) to apage.php however if there are any errors in your coding, the error style of PHP will let user know that you are using php

They are actually both language constructs (printf() is a function)The main difference is that print returns a value, so you could do something other than simply display the string. This makes it a little slower than echo.Unless you need the return value, use echo. Plus, it's easier to type!

What is the difference between echo and print statement?
bluemonk
- Aug 31st, 2008
Both echo and print are language constructs. However print() acts like a function in that it returns a value and can be used in complex expressions.Furthermore, echo without parentheses can take multiple arguments. Echo with parentheses and print can only take a single argument.
