PHP Syntax

PHP Syntax

You cannot view the PHP source code by selecting "View source" in the browser -you will only see the output from the PHP file, which is plain HTML. This is because the scripts are executed on the server before the result is sent back to the browser.

Basic PHP Syntax

• A PHP scripting block can be placed anywhere in the document.
• On servers with shorthand support enabled you can start a scripting block with .

• However, for maximum compatibility, we recommend that you use the standard form rather than the shorthand form.
• A PHP file normally contains HTML tags, just like an HTML file, and some PHP scripting code.
• Each code line in PHP must end with a semicolon. The semicolon is a separator and is used to distinguish one set of instructions from another.
• There are two basic statements to output text with PHP: echo andprint. In the example above we have used the echo statement to output the text"Hello World".

Comments in PHP

• Comments are use to ignore code or codes of line from the execution on the server. 
• In PHP 2 types of comments are available.
• Single line comment, Multiline comment.
• Single line comments can be given by // or #.
• Multiline comment can be given by /*..........*/.
