PHP Tutorial for novices - The Syntax
Definition of syntax
Syntax - The rules governing the formation of statements in a programming language. The PHP syntax is similar to other programming languages, like C, Java or Perl, so if have some experience with other languages, you'll feel right at home in PHP.

PHP code is contained within an opening and closing tag, like this:

?>

You may also use the shorthand variant, like this
<?php
... php code ...
?>
Inserting comments
There are two ways of inserting comments in PHP. One is adding two forward slashes, which comments out any text after the slashes until the end the line, and the other is to contain the comment within /* and */ to make a large comment block.Example:
<html>
<body>
<?php
//This is a comment
/*
This is a
comment block
*/
?>
</body>
</html>
The semicolon
The semicolon is special in PHP as it marks the end of a command and is typically used at the end of each sentence in PHP scripts that you download. Spaces are ignored, so the following command:
echo "Hello World";
echo "Hello World" ;
