PHP

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

  1. Get the current URL

    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)

  2. 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.
