Examples
PHP is written inline with HTML documents, making it ideal for people who have experience with designing websites with HTML/CSS and want to create a more dynamic web experience. PHP is processed by the server before it is rendered in the browser.
All of the examples here assume that you have a rudimentary understanding of HTML and have webserver software installed on your system, or access to a webserver with PHP.
Hello World!
<?php echo "Hello world!"; ?>
If you put this code into a file and give it a .php extension, it will render plain text to the web browser. As you can see every piece of PHP must be opened and closed with the PHP html tags.
Date
<?php
// variable declaration
$date = date("Y/m/d");
// using the variable with the echo function
echo $date;
?>
The Date function is a great tool to show how PHP generates dynamic content. The above format displays the full year, the month and day all in numbers like so: 1999/02/16.
