Server-Side Includes vs PHP
Birdhouse supports PHP, which is immeasurably more flexible than SSI (it’s an entire language, not just a directive). There really is little need for SSI anymore. Here’s how to do the equivalent of server-side include in PHP:
<?
include "/home/username/public_html/somefile.txt";
?>
Need the date and time inserted in your page at runtime? Try this:
<?
$today = date("F j, Y, g:i a");
echo $today;
?>
Your pages will need to end with the .php extension to be parsed by the PHP interpreter on the server.
