Examples, hints, and tips to help you code better in PHP.

Get the current URL
- PHP
If you already know some information about the URL you can use that information to replace the respective part.

Start with an empty path

<?php $path = ""; ?>

Check for the protocol (ie. http, cgi)
If you know the protocol is http you can replace this accordingly.

<?php // SERVER_PROTOCOL is in the form "protocol/rev#", this strips the revision $path .= strleft(strtolower($_SERVER["SERVER_PROTOCOL"]), "/"); ?>

Check if secure (HTTPS)

Embed PHP into HTML

PHP code can be embedded into any HTML web page by using the <?php ?> tags.

<html>
    <head>
        <title>My PHP Page</title>
    </head>
    <body>
        <?php
            echo "Hello World!";
        ?>
    </body>
</html>

Most web servers will only interpret php code in pages with a .php file extension.
