PHP is an easy to understand server side scripting language. You can write your code in any text editor. Here is a simple piece of code that shows the basic syntax.

Each php script starts and ends with this code

<?php
   ... Your code goes here ...
?>

<!DOCTYPE html>
<html>
<body>

<?php
echo "This is my first PHP script!";
?>

</body>
</html>
