Creating a PHP Page
PHP scripts can be either imbedded within standard HTML or be used to generate an HTML page entirely. Code written in PHP is wrapped with the <?php and ?> tags. On typical web hosts, PHP documents must end with the file extension ".php".
Note: The "\n" at the end of each line is a symbol which denotes a new line. It isn't required, but it makes the source code for the resulting HTML document more readable.
Example of PHP embedded within HTML:
<html>
<head>
<title>Embedded PHP</title>
<body>
<?php
echo "Hello world!\n";
?>
</body>
</html>
|
Example of HTML page generated with PHP:
<?php
echo "<html>\n";
echo "<head>\n";
echo "<title>PHP Generated HTML</title>\n";
echo "</head>\n";
echo "<body>\n";
echo "Hello world!\n";
echo "</body>\n";
echo "</html>\n";
?>
