Notes: -Always use double quotes if you want to concatanate vars with strings.
-Whe ur using arrays in ur strings that is to be
concatenated delimit the array by { and }.
-Take a look at sprintf function to better format strings in
case ur familiar with C coding style.
-Sometimes googling might not help nor PHP.net. So, the PHP
manual is ur friend. e.g you could go to Array section in PHP manual
and find out what's up :)
