Basic PHP Syntax
A PHP script can be placed anywhere in the document.
A PHP script starts with <?php and ends with ?>:
<?php
// PHP code goes here
?>
The default file extension for PHP files is “.php“.
A PHP file normally contains HTML tags and some PHP scripting code.
Below, we have an example of a simple PHP file, with a PHP script that uses a built-in PHP function “echo” to output the text “Hello World!” on a web page:
Example
<!DOCTYPE html> <html> <body> <?php echo "My first PHP script!"; ?> </body> </html>
