.php
. This tells the server to treat this page as a PHP script.

<?php
tag, then we write our PHP code, and finally close it with the ?>
tag. This is important as if we were creating an XML file and forgot to escape the opening XML tag which also has a question mark, we would run into a fatal error.echo
statement in our PHP code by placing the text we want to echo in single quotes and then end the command with a semi colon. Let's echo out "there!":
<html>
<head>
<title>Hello</title>
</head>
<body>
Hello <?php echo 'there!'; ?>
</body>
</html>
$_GET
?name=yourname
name
in the querystring, we can use $_GET['name']
like so:
<html>
<head>
<title>Hello</title>
</head>
<body>
Hello <?php echo $_GET['name']; ?>
</body>
</html>
$_GET['name']
."if
, elseif
, and else
along with the PHP date()
function. You can learn more about how to use different date formats to output the date here, but we'll be using the date()
function to get back the hour of the day (based on the server's time) between 0 (midnight) and 23 (11pm). We'll then use greater than (>) to determine what to assign to our $time
variable which we'll output with the user's name.
<html>
<head>
<title>Hello</title>
</head>
<body>
<?php
if(date("G") > 18) {
$time = 'evening';
} elseif (date("G") > 12) {
$time = 'afternoon';
} else {
$time = 'morning';
}
echo 'Good '.$time.' '.$_GET['name'];
?>
</body>
