In PHP, a code island (or code block) contains PHP code.
Contents
Description
A PHP page commonly contains a mix of HTML and PHP code.
All of your PHP code must be inside a code island.
PHP code islands must not include HTML, CSS or JavaScript; using these languages inside a code island will trigger a PHP error.
Example
The example below shows a PHP code island inside a paragraph element:
<p> <?php echo "Hello World"; ?> </p>
The above code sample is a mix of HTML (a paragraph tag), and a PHP code island (which will display "Hello World" for the user, inside the paragraph.
The echo keyword generates the text Hello World (the text inside the quotation marks -- not the quotes themselves).
