The PHP script is executed on the server, and the plain HTML result
is sent back to the browser.
A PHP script always starts with <?php and ends with ?>. A PHP script can be placed anywhere in the document.
For maximum compatibility, It is recommend that you use the standard form (<?php) rather than the shorthand form which is done in this manner, (<? and ends with ?>)
<?php
?>
?>
A PHP file normally contains HTML tags, and some PHP scripting code.
Below, we have an example of a simple PHP script that sends the text "Hello World" back to the browser:
<html>
<body>
<?php
echo "Hello World";
?>
</body>
</html>
<body>
<?php
echo "Hello World";
?>
</body>
</html>
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".
