// PHP code goes here
?>
".php" is the PHP file extension by default.
HTML tags and some PHP scripting code are typically contained in a PHP file.
An example of a straightforward PHP file with a PHP script that outputs the phrase "Hello World!" via the built-in PHP function "echo" can be found below. on a website page:
<!DOCTYPE html>
<html>
<body>
<h1>My first PHP page</h1>
echo "Hello World!";
?>
</body>
</html>
PHP Case Sensitivity
In PHP, keywords (for example if, else, while, reverberation, and so on.), Case is not a factor in classes, functions, or user-defined functions.
In the example provided below, each of the three echo statements is legal and equal:
<!DOCTYPE html>
<html>
<body>
ECHO "Hello World!
";
echo "Hello World!
";
Echo "Hello World!
";
?>
</body>
</html>
