A
PHP scripting block always starts with
<?php and ends with ?>.
A
PHP scripting block can be placed anywhere in the document.
On
servers with shorthand support enabled you can start a scripting block with <? ?>.
For
maximum compatibility, we recommend that you use the standard form (<?php) rather than the shorthand form.
Standard
tags “<?php ?>”;
Short
tags “<? ?>”;
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:
<html>
<body>
<?php echo "Hello World"; ?>
</body>
</html>
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".
The file must have a .php extension. If the file has a .html extension, the PHP code will not be executed.
