PHP Syntax 

PHP code is executed on the server, and the plain HTML result is sent to the browser.

Basic PHP Syntax

On servers with shorthand support enabled you can start a scripting block with .

A PHP file normally contains HTML tags, just like an HTML file, and some PHP scripting code.
Below, we have an example of a simple PHP script which sends the text "Hello World" to the browser:

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 and Print. In the example above we have used the echo statement to output the text "Hello World".

Note: The File must have a .php extension. If the file has a .html extension, the PHP code will not be executed.

  echo "Hello World";
