PHP code is written within the <?php ?> tags (something similar to jsp scriptlets). These tags tell PHP to start and stop interpreting the code between them. The code between these tags are executed and the server end, and the output from these tags is plain HTML. Each PHP statement should end with a semi-colon,just like C,C++ or Java, but its option to have a semi-colon for the last line of PHP block.
